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.

$ 359.95 each
MFJ HF/VHF/UHF Antenna Analyzer

1.5-185* MHz plus 220 and 300-490MHz

All the RF-diagnostic functions you need with easy-to-use MFJ-266C digital analyzer!

The MFJ-266C covers HF, VHF, plus UHFamateur and commercial frequencies with digital precision.
It also displays SWR, Complex Impedance, and Impedance magnitude simultaneously -- all on the same
easy-to-read LCD screen. Use it to measure Capacitance, Inductance, Field Strength, Frequency, plus
generate test signals. You can also fine tune stubs, analyze coax, test baluns and RF transformers, and
perform many other important RF-related tasks around the shack or on the road!

When it comes to simplicity and convenience, MFJ-266C is a winner. Not only is it easy-to-use, but fits comfortably in one hand for on-the-fly measurements on the bench or in the field. Here`s the rundown of what this compact powerhouse can deliver:

Frequency Coverage
The MFJ-266C covers all bases -- 160 through 6 Meters, the FM broadcast band, Airband, 2 Meters, 220 MHz, 70 cm, plus VHF/UHF commercial 2-way frequencies:
Band A: 1.5 to 2.7 MHz
Band B: 2.5 to 4.8 MHz
Band C: 4.6 to 9.6 MHz
Band D: 8.5 to 18.7 MHz
Band E: 17.3 to 39 MHz
Band F: 33.7 to 65 MHz (gap*)
Band V: 105 to 230 MHz 220 MHz!
Band U: 300-490 MHz

The velvet-smooth 10:1 vernier drive and solid state varicap makes fine tuning a breeze, Built-in dial lock prevents accidental detuning making measurements. Switched backlighting LCD screen is easy-to-read in any light.

SWR, Impedance Magnitude, and Complex Impedance
In SWR Mode, MFJ-266C reads SWR 1:1 to 9.9:1, Impedance Magnitude 10-500 Ohms and Complex Impedance (resistance
and reactance). Best of all, it displays all three parameters simultaneously and operating frequency with one quick glance. No other low cost handheld analyzer offers this! (Note: Z-mag and R+jX not displayed on UHF).

Capacitance and Inductance
Find values for unknown capacitance in pF or unknown inductance in uH quickly. Measurements are made at RF frequencies
rather than at the low audio frequencies used by many handheld L/C meters.

Frequency Measurement, Field Strength Readings
In Frequency-Counter Mode, MFJ-266C becomes an accurate 500-MHz counter with a choice of 1-kHz or 100-Hz resolution. The
counter mode also features a high-resolution digital field-strength meter for measuring the relative intensity of incoming signals. Together, these functions are extremely useful for checking the operation of oscillators,
transmitters, as well as assessing the strength of radiated signals from antenna arrays.

Built-in Interference Detection
In Frequency-Counter Mode, MFJ tracks down powerful local signals that disrupt accurate SWR measurements. When picked
up by an antenna under test, these signals compete with MFJ-266C`s internally generated test signal to make SWR readings appear artificially high. Handheld antenna bridges are subject to additive interference, but only MFJ detects the offending signal, displays severity, and identifies frequency!

Powerful Signal Source
MFJ-266C also functions as a tunable signal source, supplying about 2 Volts peak-to-peak across the entire tuning range. You can use this signal to drive mixers, low-power amplifier stages, or filters, and use it as a source for checking antenna patterns on a range. Add a step attenuator, (MFJ-762) and it becomes a low-level signal source for testing receivers and pre-amps.

Take it With You!
You`ll love the compact size and bantam weight of MFJ-266C when perched on a tower. Also, push-button band switching lets you toggle across the spectrum with ease when tucked into cramped spaces.

User-Friendly Layout
MFJ-266C is ergonomic, antenna N-connector positioned on top of the case and everything else arranged and clearly marked on front panel -- right in front of your eyes.
MFJ-266C’s operating manual was professionally written and illustrated to help you understand and master every function quickly. It also includes a guide for ensuring accurate results and getting the most from the unit`s advanced features. In the back, you`ll find a one-page "Quick Guide" that reviews all controls and functions.

Many Instruments in One
Having MFJ-266C is like owning several pieces of test equipment. You get a powerful wide-range signal source, Inductance/Capacitance meter, network analyzer, RF field-strength meter and a 500-MHz frequency counter all-in-one small package.

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!

Typically save over 30 watts in heat dissipation during transmit, and even 3-4 watts during receive. So it can actually be good to let the voltage sag to 12 volts, then let the MFJ-4116 protect you from lower voltages.

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.

MFJs exclusive IntelliTune™, Adaptive Search™ and InstantRecall™ algorithms give you ultra-fast automatic tuning with over 20,000 VirtualAntenna™ Memories.

MFJ VirtualAntenna™ Memory

MFJ new VirtualAntenna™ Memory system gives you 4 antenna memory banks for each of 2 antenna connectors. You can select up to 4 antennas on each antenna connector. Each antenna has 2500 memories.

4 Times the Solutions!

MFJ-929 gives you 256 values each of capacitance and inductances for 131,072 matching solutions. Thats 4 times the 32,768 matching solutions of competing products with only 128 L/C values each!

Highly intelligent, ultra-fast tuning!

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 its not faster.

MFJ`s faster speed comes from advanced technology and software algorithms not from fewer matching solutions.

MFJ`s IntelliTuner-Compact™ 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, AdaptiveSearch™ determines the smaller sub-set 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

An easy-to-read, two-line, 16-character backlit LCD displays SWR, peak or average forward/reflected power, frequency, antenna 1 or 2, L/C tuner values, on/off indicators and other info. They are selected from easy-to-understand menus; not complex combinations of buttons you can`t remember.

A fast-response, high-resolution bargraph gives you an auto-ranging 20/200 Watt power meter. You get 60 segments each for forward and reflected power and 36 segments for SWR -- try that with an 8 segment bargraph that makes you change power ranges and doesn’t even give you reflected power!

You can read inductance and capacitance directly in uHy and pF. This turns you into an expert L-network designer! Match your load, read the resulting L/C values, then use them to build your fixed L-network.
Or, knowing the L/C values you can determine R and X of the load impedance.

StickyTune™ mode gives you one-hand tuning by locking the TUNE button; just transmit to tune regardless of SWR.


Has audio SWR meter and audio feed back. Competing products don`t. Built-in 50 MHz frequency counter. Its built-in radio interface lets you use a simple wire cable to compatible rigs. Others require a cable with expensive electronics. Binding post for random wire. Self-test. Highly efficient L-network. 10 Amp/1000V relays, RF duty silver mica capacitors.

When you key your transmitter, MFJ`s InstantRecall checks to see if that frequency has been used before. If so, tuning is instantaneous. If not, MFJ`s IntelliTune algorithm (based on MFJ`s efficient SWR Analyzer technology) measures the impedance, snaps the necessary components in place, and then fine-tunes the SWR. If the antenna impedance is outside the tuner`s measurement range, MFJ`s Adaptive Search algorithm measures the frequency and determines only relevant component values -- which are then searched for fast tuning.

Safe Automatic Tuning and Amplifier Protection

The MFJ-998 includes MFJ’s Amplifier Bypass Control -- an MFJ exclusive feature! When used with a transceiver interface cable, tuning is safe and "stupidproof"! When a tuning cycle is initiated, the MFJ-998 first bypasses any in-line amplifier. Next, the MFJ-998 initiates a low-power CW tuning carrier from your transceiver. When tuning is complete, the MFJ-998 reverts your transceiver to its prior power and mode, and re-enables the amplifier. This entire cycle typically takes less than a second! Finally, if the MFJ-998 cannot find a match better than a preset amplifier SWR trip-point, the amplifier stays bypassed to provide automatic SWR protection for your amplifier -- another MFJ exclusive!

Analog SWR/Wattmeter

A large analog Cross-Needle SWR/Watt-meter displays selectable 300/60 watt or 3000/600 watt forward/reflected full-scale ranges. You can even select automatic power ranging -- the best power range is automatically selected for you.

Digital LCD SWR/Wattmeter

A two-line, 16-character backlit LCD meter displays SWR, forward/reflected power, frequency, antenna selected, an auto-ranging bargraph power indication,
and much more. You can even read the final matching inductor and capacitor values should you want to build your own fixed matching network. Simple menus
determine displayed information - no complex button combinations to remember!
