Dual 300 / 150 Watt IntelliTuner Automatic Antenna Tuner
World’s First dual power level 300/150 Watts SSB/CW Tuner Select 300 Watt SSB/CW power level and match Ohm antennas Or . . . select 150 Watt SSB/CW power level and match extra widerange Ohms!
The MFJB IntelliTunerTM lets you tune any antenna automatically balanced or unbalanced ultra fast.
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.
MFJs exclusive IntelliTunerTM, Adaptive SearchTM and InstantRecallTM algorithms give you ultra fast automatic tuning with over 20,000 VirtualAntennaTM Memories.
You get a highly efficient Lnetwork, ohm matching at 300 Watts SSB/CW or extrawide Ohm matching at 150 Watts SSB/CW, 1. MHz coverage, CrossNeedle and digital meters, audio SWR meter, backlit LCD, remote control port, radio interface, heavyduty 16 amp/1000V relays.
As you’re ragchewing, contesting or DXing, your MFJB is learning! When you transmit, the MFJB 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 VirtualAntennaTM 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.
MFJs InstantRecallTM 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 IntelliTunerTM algorithmbased on MFJ s famous SWR Analyzer technologykicks 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 MFJB is the fastest automatic antenna tuner in the world.
If it can’t accurately determine impedance, MFJ’s AdaptiveSearchTM algorithm goes into action. Frequency is measured and relevant components values are determined. Only those values are searched for ultrafast tuning.
For even faster searches, you can set the target SWR to 2 (settable 1..0). You can manually tune when you can’t transmit (for listening out of ham bands).
Lighted CrossNeedle 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.
An easytoread backlit LCD displays SWR, forward/reflected power, frequency, antenna 1 or 2, L/C tuner values, on/off indicators and other information.
The MFJB is a compact 10Wx2¾ Hx9D inches. Use 12 –15 VDC/1 amp or 110 VAC with MFJ
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 antennahorizontal loops, vertical loops, multiband doublets, quads, folded dipoles, Zepps.
