The mfj-993b dual 300 / 150-watt intellituner automatic antenna tuner. The world’s first dual power level 300/150 watts SSB/CW tuner -- select 300 watt SSB/CW power level and match 6-1600 ohm antennas or select 150-watt SSB/CW power level and match extra wide-range 6-3200 ohms! The mfj-993b intellituner tm lets you tune any antenna automatically balanced or unbalanced -- ultra fast. It’s a comprehensive automatic antenna tuning center complete with SWR/watt-meter, antenna switch for two antennas, and 4:1 current balun for balanced lines. You get a highly efficient l-network, 6-1600 ohm matching at 300 watts SSB/CW or extra-wide 6-3200 ohm matching at 150 watts 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 rag chewing, 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! Mfjvirtualantennatm memory system gives you 4 antenna memory banks for each of 2 antenna connectors. Elect up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 total. Intelligent ultra-fast tuning. MFJ's instant recall first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous 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 adaptive search 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 let 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 bar graph 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 10wx2¾ hx9d inch. Use 12 –15 vdc/1 amp or 110 vacs with mfj-1316. Tune any antenna. You can tune any antenna — dipoles, verticals, beams, phased arrays, inverted vees, quads, random wires, mobile antennas, compact limited space antennas. A 4:1 true current balun lets you tune any balanced antenna. Horizontal loops, vertical loops, multi-band doublets, quads, folded dipoles, zeps.
