It's a comprehensive automatic antenna tuning center complete with SWR/Wattmeter, antenna switch for two antennas and 4:1 current balun for balanced lines.

MFJ's exclusive IntelliTuner, Adaptive Search and InstantRecall algorithms
give you ultra fast automatic tuning with over 20,000 VirtualAntenna Memories.

You get a highly efficient L-network, 6-1600 ohm matching at 300 Watts SSB/CW
or extra-wide 6-3200 Ohm matching at 150Watts SSB/CW, 1.8-30 MHz coverage, Cross-Needle and digital meters, audio SWR meter, backlit LCD, remote control port, radio interface, heavy-duty 16 amp/1000V relays.

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

MFJ's 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, 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-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.

Backlit LCD Display

An easy-to-read backlit LCD displays SWR, forward/reflected power, frequency,
antenna 1 or 2, L/C tuner values, on/off indicators and other information.
The MFJ-993B is a compact 10W x 2¾H x 9D inches. Use 12 -15 VDC/1 amp or 110 VAC with MFJ-1316.

Remote Control Plug in the MFJ-993RC, remote control and use your tuner elsewhere remotely.

MFJ 993B IntelliTuner™ Automatic Antenna Tuners

MFJ 993B IntelliTuner™ Automatic Antenna Tuners facilitate tuning any antenna automatically; balanced, unbalanced, or single-wire.

MFJ 993B tuners are comprehensive automatic antenna tuning centers with an SWR/wattmeter, a built-in antenna switch for two antennas, and a 4:1 current balun for balanced lines. They may be operated at a remote distance through a 9-pin to 9-pin computer cable using the MFJ-993RC remote control unit.

MFJ's exclusive InstantRecall™, IntelliTune™, and AdaptiveSearch™ algorithms provide fast automatic tuning with more than 20,000 non-volatile VirtualAntenna™ memories. Each of the two antenna ports have four banks of memory; each memory bank has over 2,500 non-volatile memories for tuner settings.

These tuners include a highly efficient switching L-network with wide matching capability, 1.8 to 30 MHz coverage, cross-needle power meters, a backlight LCD screen, a port for an accessory remote control, a radio interface port, and heavy-duty 16 amp/1,000 V relays. They are rated at 300 watts to match 6 to 1,600 ohm antennas (SWR up to 32:1) or 150 watts to match wider range of 6 to 3,200 ohm (SWR up to 64:1) antennas. A maximum of 256 values of inductance and 256 values of capacitance is available. With the capacitance switched between the input and output side, this provides a total of 131,072 L/C tuning combinations. The nominal tuning ranges are 0 to 24 microhenrys and 0 to 3,900 picofarads.

All MFJ IntelliTuners™ learn and remember. When you transmit, they automatically adjust for minimum SWR and remember the frequency and tuner settings, then safely store them in non-volatile memory. The next time you operate on that frequency (or close to it), tuner settings are instantly restored and you're ready to operate in milliseconds.

MFJ 993B IntelliTuner™ features include:

  • Automatically matches antennas with impedance of 6 to 1,600 ohms or 6 to 3,200 ohms (depending on power level)
  • Handle 300 watts (match 6 to 1,600 ohms) or 150 watts (match 6 to 3,200 ohms)
  • Initially tune in less than 15 seconds, usually less than 5 seconds
