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.

MFJ-266C
HF/VHF/220MHZ/UHF ANTENNA ANALYZER


$ 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.

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.

It learns while you’re having fun
As you’re ragchewing, contesting or DXing, your MFJ-993B is learning!

When you transmit, the MFJ-993B automatically tunes for minimum SWR and remembers your frequency and tuner settings. 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 new VirtualAntenna Memory system gives you 4 antenna memory banks for each
of 2 antenna connectors. Select up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 total.

Intelligent ultra fast tuning

MFJs InstantRecallTM first checks its memory to see if you have operated this frequency before. If so, tuning is instant-aneous and you’re ready to operate.

If not, MFJs 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-993B 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 components 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 1.0-2.0).

You can manually tune when you can’t transmit (for listening out of ham bands).

Cross Needle and Digital SWR/Watt Meters

Lighted Cross-Needle and digital meters lets you accurately read SWR, forward and reflected power at a glance.

An audio SWR meter lets you hear the tuned SWR when you can’t see/read meters.
Turn on a highly visible, instant response SWR LCD bargraph when you need it.
