Powermaster Battery Isolator
Battery Tender Systems
We’ve all been there: a busy Field Day
or DXpedition. You make plenty of contacts while
your gear sips a steady diet of voltage from your
car’s auxiliary battery. When it’s time to leave—your car won’t start!
Using an auxiliary battery doesn’t always protect your primary battery from draining.
Powermaster’s Battery Isolator prevents this unwanted drain. It ties your batteries
together, allowing them both to charge from your engine’s alternator. Since your
auxiliary battery is isolated, it won’t drain the charge from your primary battery in the
event of excess load.
Use Powermaster’s Battery Isolator when you’re operating off your vehicle’s battery
power and keep yourself from being stranded.

AC/DC
Power Protectors
Proper protection from lightning strike power surges is
accomplished on two levels: First, an AC shunt protector should
be installed at your single point ground (SPG) location. Second,
connect your gear to an AC Series protector, also tied to SPG.
Keeping your equipment plugged into the same outlet and
grounded to the same point is the best way to ensure that it is
all at the same electrical potential.
Polyphaser offers excellent AC Series Protectors that install
in-line with your sensitive equipment. These protectors have
a master on/off switch and circuit breaker for extra protection. They can also handle
multiple strikes. The housing mounts to the DXE-CU-SPGP grounding plate and ties the
plate to your SPG.

Surge Protection Products
A power surge can enter your home through any electrical conductor. Whether it’s a
power grid anomaly or a lightning strike, you can protect your home. Even independent
electrical circuits (a telephone line for instance) share ground paths—which opens the
door for power spikes to enter every electrical device you’ve plugged in to your home’s
AC outlets. To help protect yourself from hazardous voltage spikes, DX Engineering offers
several surge protection options.
DX Engineering
Utility Enclosure Package
The Utility Enclosure Package is a
high-impact thermoplastic enclosure
ideal for outdoor mounting of all types of
lightning protectors or other equipment.
Its weather-tight design protects the
components from rain and direct water
spray. It resists degradation from environmental contaminants, chemical fertilizers
and insecticide sprays that can ruin metallic
housings.
The thermoplastic housing and wire entrance grommet
material fire retardant and UV stabilized. The enclosure can
be painted with latex or oil base paints if needed to blend it in with its location.
Mounting hardware, aluminum component mounting plate, and four weather tight
large feed-through grommets for RG-213 and LMR-400 sized cable are included.
Optional feed-through grommets for smaller cables are available. Exterior dimensions:
13" W x 14" H x 4" D.

Transi-Trap
Broadband Coaxial
Surge Protectors
These gas surge arrestors protect sensitive equipment from
the excessive voltage and current caused by static buildup or a
lightning strike. The 50 Ω DC voltage pass-through design is
perfect if you’re using coaxial cable to carry both RF and DC voltage,
like in an antenna switch. These protectors use a replaceable Arc-Plug™
cartridge that you can change in the field without tools. They feature a
1/4"-20 mounting stud for easy install.
The Defense Logistics Agency has assigned National Stock Number (NSN) 5920 01 5470278
to the model TT3G50 Coax Surge Protector and NSN 5325 01 5466841 to the 3G50 Arc-Plug
cartridge for use in all U.S. Military and NATO applications worldwide.

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.

DX Engineering U-Bolt Saddle Clamps
Our U-Bolt Saddle Clamps are ideal for use with round tubing. Unlike common hardware store clamps that are sized to fit
pipe, our clamps are designed and sized to fit tubing.
The U-Bolt Saddle Clamps come with high strength, 18-8 grade stainless steel U-bolts that are long enough to attach
tubing or components to thick mounting plates. The U-bolts are available in 1/4 inch, 5/16 inch and 3/8 inch as listed. Note
that the 2 inch, 2.5 inch and 3 inch clamps are available with either 5/16 inch or 3/8 inch U-bolts.
The U-Bolt Saddle Clamp saddles are cast from high strength 535 aluminum, which has superior anti-corrosion properties.
Unlike stamped or machined types, the saddles’ rippled surface grips tubing closely for a secure fit.
The U-Bolt Saddle Clamps are designed for use with mounting plates, which are available separately.
The clamps are sold only as a set with aluminum saddle, stainless steel U-bolts, nuts, flat washers and
lock washers.
The use of a lubricant and sealant, such as Never-Seez®, is highly recommended to achieve proper torque and prevent
galling. DX Engineering sells replacement U-bolts with hardware kits.

Saddle clamps must be used on a flat surface or customer
supplied backing plate. Personal injury and property damage
can occur without proper installation. Always use a lubricant
such as Never-Seez® or Anti-Seize to prevent the stainless steel
hardware from seizing.
DX Engineering Clamps Have Hundreds of Uses!
DX Engineering U-Bolt, V-Bolt, and Band Clamps are very
versatile. For example, we’ve seen the ECLS Studded
Band Clamps used to fasten merchandise display signs
to upright tubing. Have you used DX Engineering clamps
for other, non-antenna projects?
We’d love to know about it—drop us a note and send
pictures if you have them!
Suggested Hole Size: 0.266" is letter “H” drill bit, 0.332" is letter “Q” drill bit, and 0.397" is letter “X” drill bit. All U-Bolts are formed from premium 18-8 stainless steel.
All Saddles are cast 535 aluminum. All Saddle Clamp Sets are supplied with 18-8 stainless steel nuts and lock washers. Dimensions shown are in inches. Note: These are NOT Automotive Muffler Clamps.
DX Engineering V-Bolt Saddle Clamps
Incorrect
Our V-Bolt Saddle Clamps are sized to fit ranges of tubing. The V-bolts are long enough
to attach tubing or components to thick plates and are highly corrosion-resistant.
The V-Bolt Saddle Clamps are intended for use with a backing plate or mounting plate to
retain the bolt spacing. The saddles’ rippled surface will clamp tubing securely to a flat surface.
Features
• 18-8 stainless steel V-bolts with nuts, flat washers and lock washers
• Cast aluminum saddles with rippled surface
• Available in a number of size ranges
Tubing Recommendations
DXE-CAVS-1P: fits 1/2 inch to 1 3/4 inch O.D. tubing, 1/4-20 bolt
DXE-CAVS-11P: fits 1/2 inch to 1 3/4 inch O.D. tubing, 5/16-18 bolt
DXE-CAVS-2P: fits 1 inch to 2 inch O.D. tubing, 5/16-18 bolt
DXE-CAVS-3P: fits 2 inch to 3 inch O.D. tubing, 3/8-16 bolt
The clamps are sold only as a set with aluminum saddle, stainless steel V-bolts, nuts, flat washers and lock washers.
The use of a lubricant and sealant, such as Never-Seez®, is highly recommended to achieve proper torque and
prevent galling. For high torque load applications where the tubing is subjected to twisting motion, we recommend
using our U-Bolt Saddle Clamps.

Super Duty Saddle Clamps
Our Clamps are Specified by
Scientific, Military &
Government Designers!
Used by Antenna Builders: Both
Commercial & Amateur!
Our Super Duty Saddle Clamps are designed for applications where maximum clamping
ability is needed. Super Duty Saddle Clamp Kits are constructed of two corrosionresistant A356-T6 cast aluminum saddles with a cast stainless steel reinforcement plate.
These clamps are the correct size to fit tubing closely and their rippled surface will grip
the aluminum tubing for a secure fit that resists the ravages of weather.
Due to the wide variety of clamping applications where a Super Duty Saddle Clamp
would be beneficial, we do not include mounting hardware, but we do offer armorcoated bolt sets separately. Super Duty Saddle Clamps are made to fit 3 sizes of tubing:
2 inch O.D., 2.5 inch O.D. and 3 inch O.D.
The use of a lubricant and sealant, such as Never-Seez®, is highly recommended to
achieve proper torque and prevent galling.

Highest Quality—Lasting Performance!
DX Engineering is famous for its Saddle
Clamps—the ones with stainless steel
U-bolts or V-bolts and matching cast
aluminum saddles. The U-bolts are the
exact size for inch-sized tubing O.D.; the
saddles feature an as-cast roughness that
keeps the tube from sliding.
Our Super Duty Saddle Clamps are
designed for applications where maximum
torque is needed to control large or
unbalanced antenna arrays, or for other
applications where other torque control
products have proven inadequate.
Our Resin Support Blocks are useful
for securely mounting tubing to any
flat surface while providing electrical
insulation.
Whether you are building a Yagi from
scratch, refurbishing a well-used “old
friend,” or experimenting with a new
antenna project, DX Engineering can
supply the best hardware for your
application. You can find useful tips
and complete dimensions for each clamp
and bracket type at DXEngineering.com.

Resin Support Block Clamps
Our Resin Support Block Clamps are ideal for securing mounting brackets or plates
to tubing, while also providing electrical insulation. That makes the clamps a good
choice for electronic components. The clamps are sturdy and provide a strong,
well-insulated mounting that is easy to construct. They are available in many sizes
for most any project you might have—see chart below.
The Resin Support Block is shown with an optional stainless steel reinforcement
plate. These plates provide additional stiffness and can also be used as sturdy
hole-drilling templates.
