MFJ TrueCurrentBalunTM
reduces feedline radiation
Most tuners use a voltage balun that
forces equal voltages on the two antenna
halves. It minimizes unbalanced currents
only if the antenna is perfectly balanced -- not
the case with practical antennas.
The MFJ-986 uses a true current balun to
force equal currents in the two antenna halves
-- even if the antenna is not perfectly balanced!
The MFJ TrueCurrentBalunTM gives superior balance over voltage baluns and minimizes unbalanced current. This reduces field
pattern distortion, concentrates your power for
a stronger signal -- plus it reduces TVI and
RF in your shack caused by feedline radiation.

MFJ Artificial RF Ground
Places your rig near earth ground potential!
Ship Code A
Create an
ground with
this MFJ-931! It effectively places your
rig near actual earth ground potential even
if your rig is on the second floor or higher
with no earth ground possible! It electrically places a far away RF ground at your rig.
How’s your RF ground? Do you have
RF “hot spots” that “bite” you when you
transmit? Do you have RF feedback that
causes your rig to quit working on some
bands? Do you have TVI/RFI that makes
your neighbors hard to live with? Do you
get weak signal reports because of extreme
ground losses or radiation pattern distortion?
These problems could be caused by
poor RF grounding, especially if your rig is
on a second floor with no ground at all.
Even if you have a good ground, a long
connection wire can ruin its effectiveness
by isolating true RF ground from your rig.
New! 4 Foot Ground Rod
Durable four foot copper bonded
steel earth ground rod is a
tough 3/8 in. diameter that
$ 95
will last and last. Sharp
Ship Code B
pointed end makes it easy
to drive into the ground. Use it to tie
your equipment to a single earth ground
to help bleed off static and RFI and prevent RF hot spots. Use several to form
a good RF ground for random, long
wire and vertical antennas.
Continued . . . MFJ-931 creates an
artificial ground! It resonates a random
length of wire thrown along the floor
and produces a tuned counterpoise. This
artificial ground effectively places your
rig near actual earth ground potential
with no earth ground possible. Reduces
the electrical length of the ground connection wire to virtually zero by tuning out its
reactance. MFJ-931 connects between your
rig and a random length of wire or a connecting ground wire. It’s tuned for maximum ground current using the built-in RF
ammeter. 1.8 to 30 MHz. 71/2Wx31/2 Hx7D

4 Times the Solutions!
MFJ-929 gives you 256
values each of capacitance
and inductances for 131,072 matching solutions. That's 4 times the 32,768 matching
solutions of competing products with only
128 L/C values each!
Highly intelligent, ultra-fast tuning!
The MFJ-929 IntelliTuner-CompactTM
lets you automatically tune any coax fed or
random wire antenna 1.8-30 MHz at full
200 Watts SSB/CW. It can match 6-1600
Ohms (SWR up to 32:1) - - that's a 50%
wider matching range at a higher power
level than lesser competing products.
You get a digital SWR/Wattmeter with
backlit LCD, antenna switch for 2 antennas, built-in radio interface and built-in
internal BiasTee for remote tuner operation.
MFJ's exclusive IntelliTuneTM, Adaptive
SearchTM and InstantRecallTM algorithms
give you ultra-fast automatic tuning with
over 20,000 VirtualAntennaTM Memories.
Don't be fooled by competing products
claiming fast search times -- if you have a
quarter of the matching solutions, of course,
it takes less time to finish but it's not faster.
MFJ's faster speed comes from
advanced technology and software algorithms not from fewer matching solutions.
MFJ's IntelliTuner-CompactTM actually
measures complex impedance -- R and X -of your antenna, computes the L-network
values needed and snaps in those components to give you an instant match.
If the load is out of measurement range,
AdaptiveSearchTM determines the smaller subset from all solutions that can match a safe
load -- and then searches only that subset -others search through far more solutions.
Digital LCD SWR/Wattmeter
MFJ new VirtualAntennaTM Memory system gives you 4 antenna memory banks for
each of 2 antenna connectors. You can

Tuning your mobile screwdriver antenna
couldn’t be easier or more reliable!
The MFJ-1924 lets you save 10 of your
favorite screwdriver antenna positions in
memory -- that’s more than enough for all
HF bands. Then, with a push of a button,
you can quickly return to any saved position.
Up/Down buttons let you manually
move the antenna to any desired position.
A 4-digit turns counter gives you precise
antenna position -- you can
see its super bright LEDs even
in direct sunlight!
Returning to a position
from memory is extremely
accurate for three reasons . . .
A. The antenna always moves to its
desired position from the bottom, insuring
that the motor is always loaded the same -moving the antenna up is harder than moving it down. It’s harder to walk up a hill
than down a hill.
B. MFJ’s exclusive AutoParkTM feature
automatically bottoms your antenna for
parking in your garage and resets and calibrates your counter each time to eliminate
antenna slippage and turns count errors.
C. The momentum of the moving antenna causes it to overshoot its stop point.
MFJ’s exclusive Dead-OnSTOPTM feature
automatically reverses the motor briefly
just before it stops to eliminate overshoot
and come to a precise stop.

MFJ Speech Intelligibility Enhancer
...makes barely understandable speech highly understandable!
Ship Code B
“What did you say?”
Can you hear but . . . just can’t always
understand what people are saying?
As we get older, high frequency hearing
loss reduces our ability to understand speech.
Here’s why . . .
Research shows that nearly half the
speech intelligibility is contained in 1000 to
4000 Hz range, but contains a miniscule 4%
of total speech energy.
On the other hand, the low frequencies,
125 to 500 Hz have most of the speech energy
(55%) but contribute very little to intelligibility -- only 4%.
To dramatically improve your ability to
understand speech, you must:
First, drastically increase the speech energy above 500 Hz, where 83% of the speech
intelligibility is concen-trated.
Second, drastically reduce speech energy
below 500 Hz where only 4% of speech intelligibility lies.
The MFJ616 splits the
audio speech
band into four
octave ranges
centered at 300, 600, 1200 and 2400 Hz. You
can boost or cut each by nearly 20 dB.
A balance control and separate 21/2 Watt
amplifiers let you equalize perceived loudness
to each ear so both ears help.
By boosting high and cutting low frequencies and adjusting the balanced control, speech
that you can barely under-stand become highly
Even if you don’t have high frequency hearing loss, you’ll dramatically improve your ability to understand speech.

effect at best, but I was astonished . . . The result
was remarkably clean, understandable speech

Protects your sensitive receiver input
from damage (including switching diodes
and attenuator resistors) caused by very
strong signals from multi-transmitter,
multi-band operation -- contests, field-day,

intermod problems.
MFJ’s unique Hi-Q series tunable circuit gives you superb performance.
The tunable series tuned circuit works

MFJ's DX Beacon Monitor lets you
see which beacon you're hearing on your

and where to point your antenna.
It's fascinating to hear and watch each
beacon location light up as they become
active across the world. Great for
DXers, contesters, ragchewers and
The International Beacon Network provides a reliable source of signals for determining HF propagation 24 hours a day.
It consists of 18 beacons around the
world. Each beacon transmits on 14.1,
18.11, 21.150, 24.93 and 28.2 MHz. The
transmit sequence moves westward from
New York across North America, Asia,
Pacific to Africa, Europe, South America.
On each frequency, each beacon trans-
mits for ten-seconds -- its call sign at 22
wpm CW and a one-second dash at 100
watts and three one-second dashes at 10, 1,
and 0.1 watts.
When each beacon completes a transmission it goes silent on that band and
switches to the next higher band.
For more information see Oct/Nov, 1994,
Sept, 1997 QST and Jan 1999, Sept/Dec
2001, Jan 2002 Practical Wireless of U.K.
The more beacons you hear, the more
open the band is to different parts of the
The more dashes you hear per beacon,
the better the quality of propagation and the
more robust the band is. If you hear the
100 milliwatt dashes from many beacons
you know the band is wide open!
In just three minutes you'll know how
band conditions are worldwide.
You don't have to copy CW at 22 wpm
to identify a beacon. As you hear a beacon, an LED instantly lights on a world
map to show you its location. You can positively identify each beacon -- even if the
signal is weak, fluttery or distorted.
The MFJ DX Beacon Monitor has a
built-in WWVB atomic clock receiver to
provide ultra precise synchronization with
the GPS-synchronized beacons. You also
may manually sync the Monitor (the

An extra long 10 foot (19” collapsed)
telescoping whip lets you really get out and
work rare DX! A 4½ foot (23” collapsed)
telescoping stainless steel whip is included
for mobile and limited space operation.
It has a highly efficient loading inductor.
For highest Q, the coil is wound with
heavy gauge wire with wide spaced turns
on a core that is mostly air.
A tuning sleeve electrically removes
turns to eliminate detrimental self-resonance effects that "wander leads" cause.
The tuning sleeve is on the low impedance side of the coil to minimize power
robbing stray capacitance and detuning
hand capacitance effects. Tuning is
smooth, easy and sure -- the frequency
stays put after you tune it. No tedious
back & forth trial & error tuning procedure.
It's extremely rugged -- the whole
coil assembly is one unit and does not
move. A separate movable sleeve adjusts
frequency. A nylon-tipped thumbscrew locks sleeve. Wing nut lets you
connect a matching capacitor or inductor
for 1:1 SWR. Standard 3/8x24 mounting hardware is used for loading coil
and both whips. Use any 3/8x24 mount.

radio was king and brought back to life
some of the most popular, classic antennas that gave the most powerful signals.
These classic high-performance antennas give you a powerful, booming signal
and needs just two trees to hang and play!
We have updated them with stronger,
more durable modern materials, adapted
some to simple, direct coax feed and made
them hang and play.
Two and Four Element Arrays
These MFJ-62XX single band two halfwave element collinear array gives you
nearly 2 dB gain -- about 150% power gain
-- and twice the receiving capture area of a
half-wave dipole. They have direct coax
feed and low SWR across the entire band.
The MFJ-64XX four half-wave element
collinear array gives you a whopping 4.5
dB gain -- about 300% power gain. You get
four times the receiving capture area of a
half-wave dipole -- you’ll hear DX you’ve
never heard before! They require a balanced line tuner or a tuner with balun.
Hang and PlayTM!
You can virtually hang and playTM when
you receive them. No cutting, soldering,
tuning, or trimming is required. Just follow
the easy installation instructions and you’ll
be up and running in no time!
They are completely assembled and
include super strong custom fiberglass center insulators, authentic glazed ceramic end
insulators, heavy duty 7-strand, 14 gauge
hard copper element wire and extremely
strong, solderless, crimped construction.
DX the World!
With the larger capture area and power
gain, you’ll hear and work more DX than
ever before!

These Antennas are Quiet!
Their directional properties and polarization reduce noise up to two to three Sunits below verticals and inverted vees.
Simple Installation
These antennas work well even at a 1/4
wavelength above ground, but perform best
at 1/2 to 3/4 wavelength above ground. They
should be mounted horizontally and pulled
tight. Lengths are 55 to 136 feet horizontally.
The feedline and stub simply hangs from
the antenna and can be bent at the bottom
or pulled away at an angle to make installation convenient. Some twisting of the feedline or stub is okay.
Worldwide Coverage

A pair of these antennas at right angles
can provide worldwide coverage. These

You can hardly see this mini 14
foot rotatable dipole across the street!
Its tiny 7-foot turning radius fits
on the smallest roof -- it’s perfect for
town houses, apartments and condos.
The MFJ-1775 is inconspicuous
and low profile -- not much bigger
than a TV antenna and can easily be
turned by a lightweight TV rotator
(see AR-35, page 63).
It’s no Wimp! Its directivity reduces
QRM/noise and lets you focus your
signal in the direction that you want
-- so you can work some real DX.
You can operate 6 bands -- 40, 20,
15, 10, 6 and 2 meters -- and run full
1500 Watts SSB/CW on all HF bands!
Features automatic
band switching and uses
highly efficient end-loading with its entire length
always radiating. With 6
and 2 Meters thrown-in, you have
ham radio’s most versatile rotatable
Each HF band uses a separate,
efficient end-loading coil wound on
fiberglass forms with TeflonTM wire,
and capacitance hats at each end (no
lossy traps). 6 and 2 meters are fulllength halfwave dipoles.
Built-to-last -- incredibly strong
solid rod fiberglass center insulator
and 6063 T-6 aircraft strength aluminum tubing radiator.
Assembles in an afternoon.
Adjusting one band has little effect
on other bands.

HyTower-Jr. is the world’s
best* performing vertical!
Stub-decoupling is used to give full-size
quarter wave radiators on 40, 20, 15, 10 Meters
with super efficient cage loading on 80 Meters.
The HyTower-JrTM has almost no losses -your ground system determines your efficiency.
It is automatic bandswitching, fed with 50
Ohm coax and has low SWR over an exceptionally wide bandwidth with SWR less than
1.2 at resonance.
The main radiator is aircraft high-strength, heavy
walled, 2-inch aluminum tubing swedged at the
top. Self-supporting in winds up to 40 MPH.
Mounts on 11/4 inch plumber’s pipe. Heavy
duty components will give you years of trouble-free operating pleasure.
Requires good ground system for optimum
performance. UPS Shippable.
*The famous 53 foot Hy-gain HyTowerTM is
legendary. It’s the premier, best performing vertical in the world -- bar none! At less than half
the price with nearly the same performance and
based on the same principles, the HyTower-JrTM
is the poor man’s version of its father HyTower (page 67).
Of course, JuniorTM doesn’t have its father’s rugged hotdipped galvanized steel tower and construction!

all parallel radiators.
This forms a very large equivalent radiator and
gives you incredible bandwidths.
Radiator stubs provide automatic bandswitching -- absolutely no loss due to loading coils or
Operate 10 bands -- 75/80, 40, 30, 20, 17, 15,
12, 10, 6 and 2 Meters with this MFJ-1798 vertical
antenna and get full size performance with no
ground or radials!
Full size performance gives high efficiency for
more power radiated. Results? Stronger signals
and more Q-5 QSOs.
Full size performance also gives you exceptionally wide bandwidths so you can use more of your
hard earned frequencies.
Full size performance is achieved using separate
full size radiators for 2-20 Meters and highly efficient end loading for 30, 40, 75/80 Meters.
End Loading
On 30, 40, 75/80 Meters, end loading -- the
most efficient form of loading -- gives you highly
efficient performance, excellent bandwidth, low
angle radiation and automatic bandswitching.
MFJ’s unique Frequency Adaptive LNetworkTM provides automatic impedance matching for lowest SWR on these low bands.
Tuning to your favorite part of these bands is
simple and is done at the bottom of the antenna.
Handles full 1500 watts PEP
Get very low radiation angle for exciting DX,
automatic bandswitching, omni-directional coverage, low SWR. Handles 1500 Watts PEP SSB.
MFJ’s unique Elevated Top FeedTM elevates the
feedpoint all the way to the top of the antenna. It
puts the maximum radiation point high up in the
clear where it does the most good -- your signal
gets out even if you’re ground mounted.
It’s easy to tune because adjusting one band has
minimum effect on the resonant frequencies of
other bands.
Self-supporting and just 20 feet tall, the MFJ1798 mounts easily from ground level to tower top
-- small lots, backyards, apartments, condos, roofs,
tower mounts.
No Ground or Radials Needed
You don’t need a ground or radials because an
effective counterpoise that’s 12 feet across gives
you excellent ground isolation.
You can mount it from ground level to roof top
and get awesome performance.
The feedline is decoupled and isolated from the
antenna with MFJ’s exclusive AirCoreTM high
power current balun. It’s wound with TeflonR
coax and can’t saturate, no matter how high your

AMERITRON's SDA-100 may be the

HF mobile screwdriver antenna in the
world! When properly installed on your
vehicle this antenna provides coverage from
80 through 10 Meters with a 6 foot whip.
Remove the whip for 40 through 6 Meters.
What makes our antennas stand above
all the rest is that our CNC machined components are from aircraft aluminum or stainless steel and blueprinted, meaning you can
take antennas apart and mix them up, then
reassemble and they all work the same.
Our fiberglass coil form is approximately 2 inches in diameter. Other antenna
builders know fiberglass is better but they
choose not to use it because of the expense
and difficulty in machining. We use 14
gauge wire for high power capability,
wound at eight turns an inch for maximum
efficiency. We machine groove our coils so
they will not loosen up or jam -- they won't
wear out, for years of trouble free service!
New Lexan cover is super durable and
protects your Ameritron screwdriver for
years of trouble-free service.
The decoupler we use is CNC machined
for tight tolerances with custom fingerstock designed to contact 3 turns of coil all
the time with over 25 pounds of combined
contact pressure. With this design you can
run up to 1.2 kilowatts PEP, trouble free.
It's so superior to anything else on the market that we put our outstanding AMERITRON warranty behind it.
We use a new heavy duty Pittman commercial 12 volt gear motor, which is very
durable and quiet while receive tuning.
This motor is super heavy duty for years of
trouble-free service. Antennas come with
the sensors already installed so if you
decide to add an auto controller now or
later, everything is ready.
The AMERITRON SDA-100 includes:
Up/Down switch; 5 feet of motor DC

Ameritron’s AL-1500 Amplifier with Eimac(R) 3CX1500A7
Feel the need for maximum legal HF output
power? AMERITRON’s
AL-1500 will give it to you.
Using the Herculean
3CX1500A/ 8877 ceramic tube with its high
power gain, the AL-1500 needs only 65
watts of drive from your exciter to deliver
the goods-- transceivers and other exciters
just loaf at 1500 watts out.
Cool, efficient operation is provided by a
forced-air system with tube chimney, using
a commercial grade die-cast ball bearing
blower for maximum tube life. The tube is
further protected by time delay starting and
automatic over-current shutoff to remove
drive power if the amplifier is mis-tuned.
You get full legal power output from a
whisper quiet desktop linear. Measures
18 /2D x17Wx10H inches, and covers all
bands, 160-15 Meters, including
WARC and MARS (80% of
full output set to nearest

You get 1500 watts
output (1/2 hour continuous carrier) and
2500 watts (30 second continuous carrier and 2500 watts$
plus 30 minute PEP two-tone test).
You get all this power, plus, 65% efficiency, pi-network tuned input, Pi/PiL output, inrush current protection,
multi-voltage transformer, QSK compatability, and a one-year warranty.

An inside look at the AMERITRON AL-1500
The AL-1500 is built on a rugged steel

fully shielded to keep RF from leaking out,
keeping RFI and TVI to a minimum.
Superb RF design and layout, Hi-Q tank
circuit and commercially rated RF power
components give you 65% plate efficiency
over the entire operating range. Power goes
into the antenna instead of into heat.
50-ohm broadband Pi-Network tuned input with slug-tuned coils is used. Even fussy
solid state transmitters deliver full power!
A carefully designed Pi/Pi-L output network using the optimum Q for each band
Ameritron’s 3CX1200A7 Amplifier
with vernier ball drives gives smooth tuning,
wide matching range, full band coverage,
and peak performance at all power levels.
The AL-1500’s grid overload circuit protects the tube from excessive grid current; if
175 mA of peak gric current is reached, the
“OPR” LED will no longer light and the
amplifier will go into a bypass condition
until reset by the operator.
Transformer provides many options
Since excessive line voltage stresses
components (low line voltage causes a “soft
tube” effect, for example), Ameritron’s
exclusive Multi-Voltage Power
TransformerTM lets you optimize for different
line voltages. Select from 4 different primary
voltage ranges, from 205-219 VAC to 252 to
265 VAC. The amplifier comes wired from
the factory for 240 VAC.
The AL-1500 has two illuminated panel
meters. Grid Current meter provides continuous reading of the critical grid current and
indicates proper, safe amplifier operation.
The other meter can be selected to read
Plate Voltage, Plate Current, Peak RF
Watts, or ALC. A SSB/CW selector switch
chooses bias voltage for best linearity on
SSB or lowest dissipation on CW.
The Operate/Standby switch, in Standby,
maintains the tube’s filament and plate voltages while allowing “barefoot” operation.
Includes 12 volt DC auxiliary jack and
