MFJ-939I
PLUG,PLAY,200W AUTOTUNER, HF,W/CABLE,ICOM


$ 159.95 each


Plug & Play Auto Tuner

Plug & Play! You won’t even know it’s there . . . MFJ-939I/K/Y automatically tunes your antenna as you tune your radio. SWR is just always low.

Tunes your coax fed or random wire antennas 1.8-30 MHz from 2 Watts QRP to full 200 Watts SSB/CW.

Matches 6-1600 Ohms (SWR up to 32:1) -- that’s a 50% wider matching range than competing products that are less capable and higher priced . . . and it’s made in the USA.

Highly intelligent, ultra-fast tuning!
As you’re ragchewing, contesting or DXing, the MFJ-939 is learning your antenna and the way you operate and storing all this in its 20,000 memories. The more you use it, the more it learns.

Measure & Compute = Instant Match
MFJ-939 uniquely measures your antenna’s complex impedance (R, X), computes the L-network and snaps in needed components for instant matching.

AdaptiveSearch
AdaptiveSearch determines a sub-set of all solutions that can provide a safe match and searches only that subset giving
you an ultra fast match. Others search slowly through all solutions.

InstantRecall
InstantRecall first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous and you’re ready to go!

MFJ VirtualAntenna Memory
MFJ exclusive VirtualAntenna Memory system gives you 8 antenna memory banks of 2500 memories each.
You can use an antenna switch to select up to 8 antennas and assign each antenna its own 2500 memories!

4 Times More Solutions and Faster!
MFJ has 256 values each of capacitance and inductance for 131,072 matching solutions giving you a finely tuned very low SWR. That`s 4 times the 32,768 solutions of competitors using only 128 L/C values each!
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 solutions.

Audio SWR Meter
An Audio SWR meter beeps when SWR <1.5, 2, 2.5, 3. Alarms if >3. Audible & Visible Diagnostic messages.

Heavy-Duty Components
Heavy-duty L-network: 10 Amp/1000V relays, RF duty silver mica caps won’t burn up. Safe, reliable, continuous 200W SSB/CW.

As Small as Your Radio

The next time you operate on that frequency and antenna, these tuner settings are instantly restored and you’re ready to operate in milliseconds!

MFJ’s new VirtualAntenna Memory system gives you 2500 memories, has a coaxial antenna connector and a binding post for end-fed long wire antennas.

Intelligent Ultra-Fast Tuning
MFJ’s InstantRecall first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous and you’re ready to operate. If not, MFJ’s IntelliTuner algorithm -- based on MFJ’s famous SWR Analyzer technology -- kicks in. It measures the complex impedance of your antenna. Next, it calculates the components it needs and instantly snaps them in. Then, it fine tunes to minimize SWR -- you’re ready to operate. It’s all done
in a fraction of a second.

When the impedance is within its measurement range, the MFJ-994BRT is the fastest automatic antenna tuner in the world!

If it can’t accurately determine impedance, MFJ’s AdaptiveSearch algorithm goes into action. Frequency is measured and relevant component values are determined. Only those values are searched for ultra-fast tuning. For even faster searches, you can set the target SWR to 2 (settable from 1.0 to 2.0).

The MFJ TrueCurrentBalun for balanced lines minimizes feedline radiation that causes field pattern distortion, TVI and RF in you shack. Ceramic feedthru insulators for balanced lines withstand high voltages and temperatures.

Replacing two variable capacitors with a single differential capacitor gives a wide range T-Network tuner with only two controls -- a tuning capacitor and a roller inductor. Simple 2-knob tuning makes tuning easier than ever. You get minimum SWR at only one setting a broadband response that ends constant re-tuning. Youll spend your time QSOing instead of fooling with your tuner. The compact cabinet has plenty of room to mount the roller inductor away from metal surfaces for highest Q -- you get high efficiency and more power into your antenna.

Wide-spaced tuning capacitor plates let you run high power without arcing. MFJs lighted Cross-Needle Meter shows you SWR, forward and reflected power simultaneously. It reads peak or average power on 2000 or 200 Watt ranges. The lamp has on/off switch nd uses 12 VDC or 110 VAC with MFJ-1312D.

More 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 TrueCurrentBalun 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-4416B
BATTERY VOLTAGE BOOSTER, 12V


$ 159.95 each
Keeps your transceiver operating at full efficiency and performance by
eliminating low or marginal voltages in the mobile environment . . .

Today`s compact 100-watt HF transceivers are designed to operate from about 12-16 volts, with output signal distortion, output power problems, and transceiver reset often occurring when voltage drops below 12 volts.

In the mobile environment, low voltage is caused in two ways: First - even low
resistance DC wiring can result in a noticeable voltage drop. For a 100-watt transceiver with a 20-amp typical current requirement, just 1/10th of an ohm resistance in your DC cable and connectors results in a 2-volt drop! And second - when you turn your car off, the battery voltage drops from around 13.8
volts to close to 12 volts after a short period of time. Couple this with any voltage drop in the cables, and you have a problem.

The MFJ-4416 Super Battery Booster eliminates low voltage problems by boosting
input voltages as low as 9 volts up to the desired 13.8 volts at up to 25 amps peak with a typical efficiency of close to 90%.

It is compact at just 7 3/4W x 4H x 2 1/8D” and lightweight at 1.3 lbs. And the MFJ-4416 Super Battery Booster is designed to be rugged, reliable, and easy to
use.

MFJ-4416 includes Anderson PowerPoleTM connectors and high-current 5-way binding posts for both the DC input and regulated output. An internal 30-amp
input fuse protects the unit from excess output current demands.

There are also selectable limits on the minimum voltage that the unit will accept: 9-volts, 10-volts (default), and 11-volts. This protects you from over-discharging a battery and possibly damaging it. MFJ-4416 also includes output over-voltage crow-bar protection should regulation be lost.

Two additional features offer ways to increase efficiency even more! First, there is an RF sampling port which can be connected to your transceiver`s transmission line with an MFJ-7733 UHF-T connector. When this feature is enabled, the MFJ-4416 is bypassed unless RF is sensed so no regulator switching efficiency penalties are incurred during receive.

The second efficiency enhancement feature is a user-adjustable output voltage control which lets you set the output voltage anywhere between 12- and 13.8-volts. When setting the output at 12-volts, input voltages greater than 12V will pass through, but the efficiency of the regulator is higher. And lower input voltage means your transceiver will run cooler!
