ANTENNA TUNER, PORTABLE/QRP, 1.8 - 30 MHZ


$ 129.95 each
The MFJ-971 is a compact 200-Watt portable tuner MFJ QRP transceivers. The MFJ-971 is also a perfect mate for any of todays ultra-compact SSB radios. It provides a convenient cross-needle type SWR/Wattmeter and features a special user-selectable 6-Watt range for QRP operation. The T-match tuner covers 1.8-30 MHz and tunes almost any coax, wire, or balanced-feed type antenna (a 4:1 toroid balun is built in for balanced line). It measures a tiny 6 x 6 x 2½ inches!


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.

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).

Determine velocity factor, coax loss in dB, length of coax and distance to short/open in feet.

Read SWR, return loss and reflection coefficient at any frequency simultaneously at a single glance. Also reads match efficiency.

Also read inductance in uH and capacitance in pF at RF frequencies.

Measure SWR and loss of coax with any characteristic impedance, 10 to over 600 Ohms, including 50, 51, 52, 53, 73, 75, 93,95,300,450 Ohms -- MFJ-269C exclusive!

415 to 470 MHz Range features

Just plug in your UHF antenna coax, set the frequency and read SWR, return loss and reflection coefficient simultaneously. You can read coax cable loss in dB and match efficiency.

You can adjust UHF dipoles, verticals, yagis, quads and other antennas and determine their SWR, resonant frequency and bandwidth.

You can test and tune stubs and coax lines. You can manually determine velocity factor and impedances of transmission lines.

Adjust and test RF matching networks and RF amplifiers without applying power.

Has easy-to-read LCD logarithmic SWR bargraph and SWR meter for quick tuning.
