Station Equipment
Surge Protection Products
A power surge can arrive by way of any conductor entering your home. One way is a
strike to the AC power line somewhere outside your home, creating a surge which
travels to your equipment via the power line. Another is a direct strike to an antenna
or tower, or a voltage-inducing near strike where energy is coupled into your antenna
system and transmission line. A surge can also enter via the telephone line. While
these sources seem to be independent, they all share ground return paths which can
co-mingle the effects of a surge on any one of them. These sources need to be
addressed to provide maximum protection for your electronic equipment.
DX Engineering provides an extensive line of lightning and surge protection products.
Alpha Delta Transi-Trap
Broadband Coaxial Surge Protectors
These gas surge arresters are designed to protect sensitive electronic
equipment from damage due to excess voltage or current generated by
lightning or static buildup. The 50 Ω, DC voltage pass-through design makes
the protectors ideal for applications requiring the coaxial cable to carry both RF and DC voltage, such as remote antenna switches that use coaxial cable for both RF and DC switching.
The protectors have a 1/4"-20 stud for easy mounting and effective grounding.
The Transi-Trap surge protectors use a replaceable ARC-PLUG™ cartridge that can be changed
in the field without tools and without removing the surge protector from the circuit.

AC/DC Power Protectors
Protecting your equipment from incoming lightning surge energy is accomplished at
two levels. Both levels require a single point ground (SPG) system.
First: install an AC power shunt protector on the incoming power mains. It is important
that the AC shunt protector is located at the SPG entry point. Second: have the equipment
connected to an AC series protector, which is also tied to the SPG. Keeping all equipment
plugged into the same outlet and grounded to the same point allows them to rise and fall in
potential at the same time with no other paths to a lower potential.
AC Shunt Protectors
For residential applications, you should use an AC shunt protector at the AC main box.
This works on AC main installations that consist of two hot, a neutral and a ground coming
from a single, center-tapped transformer, typical of most U.S. residential installations.
The AC shunt protector takes the surge energy on each hot lead to ground
rather than the neutral line. Each hot lead is protected and includes a
resettable circuit breaker on the path to ground. The AC shunt
protector also includes a dry contact alarm indicator.
AC Series Protectors
Use the PLDO line of protectors in-line to protect sensitive
equipment. The unit has a master on/off switch and circuit breaker
for added protection. It is capable of handling multiple strikes.
Mount the housing on the PPR-CU-SPGP grounding plate and tie
the plate to your single point ground.

for proper ground contact between a round
member made from copper, brass, aluminum,
tin, or steel to corresponding copper, brass,
aluminum, tin, or steel grounding material. Examples: grounding the coax shield as the
coax leaves the tower or connecting a round tower leg to the ground system. Three kits
are available for various combinations of shield material to grounding material, and they
fit coax shield or tower leg diameters from 1/4 inch to 2 1/8 inches. These kits include a
perforated strap, an adjustable angle, 24 inch long tail strap, weatherproofing kit and all
stainless steel brackets and hardware.

Ground Braid Assemblies
DX Engineering Ground Strap is available preassembled with lugs for both #10 and 1/4 inch
bolt sizes. A grounding strap is ideal for grounding a rig, amp, etc. to a copper strip running
behind the desk; the strip becomes the central ground point for the equipment. This central
ground can be routed away with heavy copper strap to join any other similarly protected
branches for single point grounding (SPG) lightning protection.
Other possible uses include noise reduction by grounding a vehicle exhaust, establishing a
connection between a radial plate, balun, and a vertical antenna to keep current off of the
feedline, and any custom grounding application where a reliable connection is needed.

Coaxial Cable Grounding Brackets
The CGB-Series Coax Grounding Brackets are a versatile solution
for additional grounding of coaxial cable shields. The stainless steel
bracket is supplied with a stainless steel V-bolt and hardware in your
choice of two sizes for a solid connection to the tower leg. Each bracket
has holes for use with DXE-363-SST bulkhead connectors, or chassis
mount SO-239 connectors, or DXE-1023 for N connectors.
The Grounding Bracket is an ideal junction point for the coax pigtails
that form the rotor loop to connect to the downleads. The bracket can
also be used at the base of the tower to provide a solid grounding point
before the coax cable is routed away from the grounded tower. The
bracket has serrated teeth to bite through paint and corrosion. Additional
fasteners are supplied if you wish to extend a ground braid or copper
strap for secure grounding.

Antenna Systems & Accessories
Maximum Isolation—
Minimum Noise!
An often-overlooked aspect of antenna systems is portto-port isolation. Poor isolation manifests itself as
receive noise being coupled from any unused antennas
to the single selected antenna. For example, if you are
using antenna #1, but antenna #7 is receiving a lot of
noise, poor isolation will allow the noise to bleed over
into your selected antenna port. There’s a lot of RF out
there—your antennas are immersed in it. Sometimes,
the signals from two or more antennas can mix up to
give you more interference issues. Poor isolation raises
your noise floor and affects your ability to receive weak
signals.
The Solution?

DX Engineering’s Symmetrical Design—
Highest Reliability and Performance!
Remote Antenna Switches
Installation of these remote antenna switches is hassle-free! There’s no need
to remove the cover to install the control cable—it plugs in with an external
connector. You can use inexpensive CAT-5 cable to connect between the
relay switch and the controller at the operator position.
The DX Engineering RF Switch also provides great SWR and superior
port-to-port isolation. To understand the importance of port-to-port isolation,
see the sidebar to the left.
DX Engineering RF Switches have a port-to-port isolation of greater than 60db
for ALL ports, not just the best port. This is the finest port isolation of all the
coax switches we have tested—and we have tested ALL of the major brands.
In fact, one particular major manufacturer’s switches tested as low as 30dB!
None of the tested switches have a port-to-port isolation as high as
DX Engineering’s switches.

DXE-PS-2B PRO-STACK
Broadband Two Antenna
Phasing System
The PS-2B PRO-STACK combines two
identical Yagi, log periodic, or vertical
antennas in a phased arrangement. It is
a broadband system that operates from
160 through 10 meters with no need for
coaxial delay lines. The PS-2B can be
used in applications requiring these four
basic antenna feed selections (impedance
matching automatically changes when
any antenna port is disconnected):
• Both antenna ports in-phase (default)
• Both antenna ports out-of-phase
• Antenna port 1 only
• Antenna port 2 only
Additional Applications
• Scalable Multi-Antenna Systems
The PS-2B easily adapts to larger arrays. For example, four stacked Yagis can be combined
by creating two sets of two and using a third PS-2B to combine the first two sets.
• Phased Verticals
The system can feed three vertical antennas in a four-pattern array. In this arrangement,
the three antennas are individual quarter-wave resonant antennas. The center #2 passive
element must be directly grounded at all times. Elements #1 and #3 are then fed in various
phase relationships.
Additional Features
• 50 Ω system—switched by applying 12-15 volts DC to three control wires
• Power handling up to 5 kW
• High-impact RF-shielded cover
• High RF-tolerant, silver-Teflon® UHF connectors
• Proven high-performance DX Engineering RF Relays
• Safe 12-volt relay operation
• MOV surge protection on control lines

Antenna Systems & Accessories
The RR2X8 is a dual-input, 8-port coaxial line switch for use in low- to medium-power RF
antenna systems, like those typically used in a single-operator/two-radio (SO2R) environment. It has the same high port-to-port isolation and reliability as DX Engineering’s famous
RR8-series single-input, 8-port remote antenna switches.
• Dual-input, 8-port, 4 kW key-down
• Excellent port-to-port isolation—
greater than 70 dB at 30 MHz worst case
• High RF-tolerant UHF connectors
• Enclosed 16 ampere RF relays
• Safe 12-volt relay operation
• 16 MOVs for surge protection on control lines
• 16 RF bypass capacitors
• High-impact, RF-shielded cover
• Includes one DXE-SSVC-2P Stainless Steel
V-Clamp for mounting
The DXE-RR2X8B is designed to interface with a customer-supplied logical switching unit,
which should provide protection against hot switching and prevent the master or slave from
attempting to select the same output port at the same time.
Manual operation is possible with two separate 1-of-8, control consoles such as the
DX Engineering CC-8A or EC-8. In this case, care must be exercised as the master
transceiver takes precedence over the slave when attempting to use the same antenna port.

Maximum Signal—Minimum Noise!
How often have you heard the old saying “If you can’t hear ’em, you can’t work ’em?”
This is never truer than when you are in the pileup calling that rare contact that you need,
wondering “Did he come back to me?”
DX Engineering provides all the tools you need to construct fabulous receiving antennas—
the kind that let you work stations that others can’t even hear! These W8JI-designed
amplifiers and antenna controllers are known worldwide for their unequalled performance.
Record-breaking DXpeditions—like VP6DX Ducie Island—know and use DX Engineering
receiving equipment. You should follow their lead and enjoy hearing those weak stations
like you have never heard them before.
Single Direction
Beverage Feed System
Active Receive
Antenna Systems
The DXE-BFS-1 is a single-wire Beverage Feed System.
This W8JI design is immune to strong signal overload
and core saturation common in multi-transmitter
contesting environments, and is used by winning
contest stations and low-band DXers. The unit uses
an isolated-winding, matching transformer system
to significantly increase the signal-to-noise ratio in
Beverage and other high impedance antennas.
The DXE-BFS-1 works with antenna impedances from
400-500 Ω. Included with the DXE-BFS-1 is a 470 Ω, 2 watt non-inductive resistor
that withstands nearby lightning strikes significantly better than hard-to-find carbon
composition resistors.
Feedline impedance on the DXE-BFS-1 is designed for 75 Ω, although it will work
with 50 Ω coax. The DXE-BFS-1 uses an industry standard CATV type F connector.
DX Engineering sells quality 75 Ω coax and type F connectors for outdoor installations.
Benefits
• 100 kHz to 30 MHz operating range
• Spark gaps minimize damage from lightning
• Wing nut terminals eliminate soldering
• Metal housings used for superior shielding and improved life
• Flange-mount holes for easy mounting
• Ground isolated secondary essential for building beverage arrays

DX Engineering’s Active Receive
Antenna Systems offer excellent
receiving performance using a
102 inch whip antenna. The unique
design is vastly superior to
traditional active antennas in
both signal handling and feedline
decoupling. You get significantly
better weak signal reception.
Available in vertical or horizontal
dipole configurations, the
systems include a non-conductive
mounting plate, clamps, active
matching system, and the 102 inch
stainless steel whip elements. The
horizontal dipole element uses two
102 inch whips for an overall length
of 210 inches; the vertical configuration
uses a single whip. Whip antennas have
excellent wind survival and are very inconspicuous.
When space is limited, use the DXE-ARAV3-1P or DXE-ARAH3-1P in conjunction with
the DXE-TVSU-1 to provide for operation within 1/10-wavelength of a transmit antenna.
The active antennas have relay protection to prevent overload of the transmit signal.
The DXE-TVSU-1A sequencer controls switching times to ensure the receive system is
protected before transmit power is applied. Use the DXE-ARAV3-4P, DXE-TVSU-1A
and DXE-RFS-2 to provide four-square operation within 1/10-wavelength of a
transmit antenna.
The vertical configuration can be used as a single element or in combination with
DX Engineering’s RFS-2 Receive Four-Square Antenna System to build a broadband
directional array that can be switched in four directions to peak the signal or null out noise.
Vertical configurations are for suburban or rural locations with low levels of ground wave
propagated noise. The dipole configuration makes a very sensitive, horizontally polarized
receiving antenna. Horizontal polarization can greatly reduce ground wave propagated noise
in congested urban environments. Light weight and low wind resistance reduces support
requirements. The output connector is a Type F, allowing use of readily available high
performance CATV feedlines and connectors (see page 40).
Features
• Sensitive—weak signal sensitivity rivaling full size antennas
• Wide bandwidth—100 kHz to 30 MHz
• Excellent strong signal handling—outstanding third order intercept of +30 dBm
• Reduced noise—quiet FET followers and high feedline shield isolation
• Easy mounting and installation—pre-drilled mounting plate and universal clamps

Reversible
Beverage System
The DXE-RBSA-1P allows two
Beverage antennas receiving in
opposing directions to share the
same space. With the DXE-RBSA-1P,
you can build a 2-wire reversible
Beverage antenna system with
superior signal-to-noise ratio, most
useful at 40, 80 and 160m bands. The
W8JI design consists of a Feedpoint
System and Reflection Transformer. You
can operate and even confirm the F/R ratio
of this antenna at any time from the
operating position.
This system is immune to strong signal overload and
core saturation common in multi-transmitter contesting
environments, and is used by winning contest stations and
low-band DXers.
The DXE-RBSA-1P has two antenna ports. The standard
configuration of the DXE-RBSA-1P has one port terminated
(termination included) so both antennas share a common
feedline. Applying 10 to 18 Vdc to the feedline switches
between the antenna, and the direction of reception. For
simultaneous reception from opposing directions, each of
the two feedlines connect to a separate receiver.
While the DXE-RBSA-1P is optimized to use 450 Ω ladder line for the antenna element,
the system will work with any 300-600 Ω 2-wire line. 450 Ω ladder line is available from
DX Engineering, sold separately. DX Engineering also sells quality 75 Ω coax and Type F
connectors for outdoor installations.
DXE-TB-5P
Benefits

2-Port Receiving
Antenna Switch
Select one of two output ports (generally connected to
different receiving antennas) from one feedline using the
DXE-RLS-2. Install the DXE-RLS-2 with two DXE-RBS-1P
Reversible Beverage Antenna Systems and select four
directions using a single main feedline. Install one or more
DXE-RLS-2s to expand larger Beverage arrays and share the
feedline back to the operating position.
Applying a nominal 12 Vac or DC control voltage through the
feedline activates transfer to port 2. Use DX Engineering’s
DXE-FVC-1 Voltage Coupler to supply the control voltage
through the feedline.
Benefits
• Metal housings used for superior shielding and improved life
• High-quality components
• Reliable CATV type F connectors standard
• Broad 0.3 to 30 MHz operating range with 75 Ω systems
• Jumper-selectable—control voltage pass-through to the selected port

Benefits
• High-quality components
• Reliable weathertight connectors
• Broad, 0.3 to 30 MHz operating range
• Metal housings used for superior shielding and improved life
• Economical solution to potential impedance errors
• Spark gaps minimize damage from lightning
Combining
Use the DXE-RSC-2 to combine, with negligible loss, two antenna systems into a single
feedline. Some examples are two antennas forming an in-phase (broadside) receiving array,
Cross-fire Echelon Beverage array, or any type of array with fixed phasing.
There are a number of advantages of using the DXE-RSC-2 for combining antenna
systems over a standard parallel connection.
• The DXE-RSC-2 matches the entire antenna system to the cable impedance
• Unlike quarter-wave matching sections that only work on one band, the DXE-RCS-2
has an extremely wide bandwidth
• With antennas connected directly in parallel, if either one develops a high impedance
open, becomes shorted, falls down or has a feedline problem, the entire antenna
system may become unusable. By using the DXE-RSC-2, only the problem antenna is
unusable—the antenna on the other port can still be used. Due to the built-in isolation
and balancing, the DXE-RSC-2 limits the total signal loss to approximately 6 dB
• The DXE-RSC-2 provides very high isolation between ports 1 and 2. This prevents
either antenna from interfering with the other during normal operation
Splitting
Use the DXE-RSC-2 to split an antenna signal in two, typically to feed two receivers.
Typical signal level reduction through the DXE-RSC-2 when used as a splitter is just over
3 dB per port. This is because each port receives half the available input power, and the
DXE-RSC-2 has some very small additional loss in internal components.
As with any system, losses are based on source and load impedances being equal. The
DXE-RSC-2 normally provides equal power, voltage, and current to matched loads on
ports 1 and 2.
The primary advantage of the DXE-RSC-2, when feeding multiple receivers from one
antenna, is that individual receiver will not seriously affect the signal level of the other receiver. This prevents receiver band filters attached to one port from “shorting” or
loading the signal of another receiver tuned to a different band. In addition, any spurious
signals generated in one receiver are greatly attenuated by the other DXE-RSC-2 before
reaching the second receiver.

Receive Feedline
Current Choke
The Receive Feedline Current
Choke (RFCC) is the most
effective solution to commonmode noise or unwanted signal
ingress in receiving systems
available. It provides thousands of
ohms isolation between the input and output coaxial shield connections while passing
desired signals, including DC or low frequency AC control signals. The RFCC has
extremely high isolation impedance, which effectively blocks common-mode noise or
unwanted signals, even in the presence of very poor grounding. The RFCC is effective
from 300 kHz to 30 MHz. It comes with standard type F female connectors, although it
can be used in any 50 to 75 Ω receiving system.

Receiver Preamplifier
This is the best HF low noise
amplifier available. The DXE-RPA-1
is optimized for a 0.3-35 MHz
operating range. The push-pull
amplifier design and robust
components enable it to
withstand high signal levels
and operate when you need it
most. The dynamic range of the
DXE-RPA-1 is better than most
receivers.
The DXE-RPA-1 is suitable for indoor or outdoor installation, with the option of being
powered through the coaxial feed. The metal housing provides shielding and improved
lifespan. The unit uses an RCA type phono jack and a Type F connector for the input and
output connections, and has a relay that automatically bypasses the amplifier when DC
power is removed.

Variable Phasing
Controller
Allows control of signal level and
phasing of two receive antennas—
see specifications below. It is available
separately for those who want to design
their own variable receive antenna system.
DXE-NCC-1
Receive Antenna Variable Phasing Controller .............................$599.95
See NCC-1 specifications below.
Typical Installation
for DX Engineering NCC-1
This diagram shows the DX Engineering NCC-1 in a station with a single
transceiver that has a separate receive antenna port. The two active receive
antennas are shown deployed in the recommended position. The DX Engineering
RPA-1 Preamplifier is normally not needed as most of today’s transceivers have
built-in preamps to compensate for overall lower signal levels obtained from small
receive-only antennas. What is most important is the NCC-1’s ability to improve
the overall signal-to-noise ratio improvement and null out interference from other
directions.
The diagram shows the transceiver keying line set up to allow the NCC-1 to shut
off the power to the DXE Active Receive Antennas, which have an internal relay which
grounds the antenna for protection from Tx RF.
The DX Engineering NCC-1 can be used with many receiving antenna combinations
including Single and Reversible Beverages, Receive Four-Square Arrays, K9AY
Loops, and more. It will increase the directivity of any properly spaced combination
of two similar antennas as long as the signal levels are within the range of the
balancing controls.
Phase two Receive antennas at proper spacing.
For optimal results, use identical antennas.
Electronically Rotatable Receive Antenna System
Phased receive-only antenna systems are used to create a directional pattern which can peak
desired signals and remove interfering signals. Variable phase nulling allows an operator to
improve reception by electronically reducing a stronger interfering signal arriving from a
different direction.
This system includes two Active Receiving Vertical Antennas and the DXE-NCC-1 Receive
Antenna Variable Phasing Unit. It combines the two verticals to produce a steerable
directional array. The system improves your reception of weak DX by:
• Combining two omni-directional antennas to produce an adjustable directional pattern
• Reducing overload from a strong signal in a different direction
• Reducing interference from distant signals or noise in a different direction
• Nulling directional strong signals to hear weak stations on the same frequency
Features
• Vertical antenna elements only 102 inches long
• Ideal for Amateur Radio or Shortwave listening
• Antenna elements are grounded when power is turned off
• Use with DXE-TVSU-1 sequencer for best protection before transmitting

Deluxe Noise Canceller
This unit is designed to reduce noise or
interference—or improve desired signals—
before the noise affects sensitive receiver
circuits. Unlike conventional noise blankers, it
is effective on all types of noise, including interference (QRM) from unwanted signals.
You can adjust both phase and amplitude while combining two antenna inputs.
The antenna inputs can be from two external antennas, or an external antenna and
the unit’s internal whip antenna. The signal output for the receiver is the vector
addition or subtraction of signals from the two separate antennas. This removes
unwanted noise and enhances desired signals.
The Deluxe Noise Canceller is optimized over the range of 1.8 to 30 MHz and has the
interface circuitry necessary for operation with most modern HF transceivers.

Receive 8 Circle
Packages
These packages are built around the DX Engineering Receive 8 Circle Array Controller and
the EC-RCA8 Receive Eight Circle Control Console. They are designed to be used with eight
identical, symmetrically-spaced vertical elements—active or passive—to provide switching
for an eight-direction receiving antenna system. (Passive elements will generally provide
you with a monoband receiving system).
The Receive 8 Circle system uses time-delay phasing (rather than conventional narrowband, frequency dependent phasing) to provide eight 45 degree-spaced directional patterns.
The time-delay phasing is directivity-optimized to produce wider and deeper rear nulls and
a narrower main lobe. The result is greatly reduced noise and undesirable signals for a
superior front-to-rear ratio (F/R). Better control of phase and currents provides a cleaner
pattern than found on vertical antenna transmit arrays.
The system also offers greater reliability in receiving applications. The RC8 controller uses
sealed relays—sized for receiving applications—with oxidation-resistant silver contacts.
Most transmitting four-square switches use large open-frame relays with exposed brass
contacts, which can lead to contamination, oxidation, and poor conductivity.
The DXE-RCA8B-SYS-2P Controller and Switch Package includes:
• DXE-RC8B-1 Receive 8 Circle Array Controller
• DXE-EC-RCA8 Receive 8 Circle BCD Control Console
• DXE-SSVC-2P Stainless Steel V-Clamp for mounting the RC8B to a 1"-2" O.D. post

Transmit Four-Square
Hybrid Controller—
4 Directions plus Omni
DX Engineering’s TFS4 Series
Four-Square Controllers combine
a high level of engineering
excellence with attention to
operator convenience and ease of
installation. The controllers are available
for 160, 80/75, and 40 meters. They
allow the operator to receive or transmit
with 5.5 dB gain in any one of four
directions with 20+ dB front-to-back
ratio for interference reduction from
unwanted directions. You can also switch
to a single omni-directional pattern with the push of a button. This
combination permits you to listen “all-around”—unhindered by pattern nulls—and
then select the best direction for signal reception and noise rejection.
The TFS4 controllers are designed for use with a four monoband vertical antenna array
spaced at the corners of a square that is 1/4-wavelength on a side. The vertical antennas
must be ungrounded and resonant in the desired band, and should be directly base-fed
by coaxial cable phasing lines from the centrally located controller. DX Engineering has
vertical antennas that are well suited for this application. Above all, a properly designed
and installed radial system is necessary for top antenna performance, whether using a
single vertical or a full array.
DX Engineering strongly recommends our optional QWC Series 1/4-wavelength cables.
They are constructed of the highest quality Belden 8213, an RG-11/U foam dielectric
cable with a velocity factor of 84% (0.84). These cables are cut to a precise electrical
length based on your choice of center operating frequency. They are terminated with
hand-soldered Silver-Teflon® PL-259 connectors and weather-sealed with shrink tubing.
Finally, each cable is tested for high voltage breakdown for maximum reliability and
power handling.
If you already have a Four-Square array with a hybrid controller (such as COMTEK
SYSTEMS, etc.) and would like to upgrade to improved performance and the Omni
feature, the DX Engineering TFS4 Series is a direct transplant. BCD logic switching
allows the use of a four-wire control cable to perform the necessary switching functions
when powered by the included DXE-CC-4SQR Control Console.
Features
• Classic Hybrid Design—easy to install
• 5 kW CW Power Rating—high reliability
• Hot Switching Lock-Out—disables amplifier while switching
• Drop-In Replacement for COMTEK SYSTEMS—easy upgrade
