MFJ-998
AUTO TUNER, 1.5KW, 1.8-30 MHZ


$ 699.95 each
MFJ 1500 Watt Legal Limit IntelliTuner

Full 1500 watts SSB/CW…Digital & Analog SWR/WattMeter . . .
All features of MFJ IntelliTuners-- Ultra-fast, Safe Automatic Tuning . . . Wide Tuning Range (12-1600 Ohms from 1.8 to 30 MHz ) . . . Radio Interfaces . . . Built-in Antenna Switch for two coax/long wire . . . Automatic Bypass protects your amplifier . . . Field Upgradeable Software . . . Very Compact!

The MFJ-998 Full Legal Limit 1500 Watt Intellituner takes you to the final level in automatic antenna tuners. With a capability of 1500 watts SSB and CW, coupled with automatic tuning, your high-power station can now operate essentially hands-free even when frequency and band changes are made.

Fast Automatic Tuning

The MFJ-998 instantly matches impedances from 12-1600 ohms using MFJ`s exclusive IntelliTune, AdaptiveSearch and InstantRecall algorithms with over 20,000 VirtualAntenna Memories. 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!

MFJ VirtualAntenna Memory

$ 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!

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.

Bullet Proof Construction
Features like the rugged aluminum case, solid-state band switching, robust internal construction, and solid-state LCD display ensure that bumps and drops won`t faze the unit in the least. Expect it to hold calibration and reliable service for years to come.

MFJ-929
200W AUTO TUNER, LCD/MTR, 1.8-30MHZ


$ 229.95 each
The MFJ-929 IntelliTuner-Compact™ 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) - thats 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.

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.

6 ½" x 2 ¾" x 7 ½". 2.4 lbs. 12-15 VDC/ 1 Amp or 110 VAC with MFJ-1316.
