MFJ's innovative Differential-T Tuner uses a differential capacitor that makes tuning easier than ever. It gives minimum SWR at only one setting. Broadband coverage ends constant re-tuning. The MFJ-986 is a rugged roller inductor antenna tuner that handles 3KW PEP SSB amplifier input power (1500 Watts PEP SSB output power). It tunes 1.8 - 30 MHz continuously, including MARS and WARC bands.MFJ's exclusive AirCore Roller Inductor gives absolute minimum SWR -- something tapped inductors just cant do. 3-digit turns counter plus a spinner knob gives precise inductance control so you can quickly re-tune your frequency. A lighted peak and average reading Cross-Needle meter shows SWR, forward and reflected power at a single glance!You get a 6-position antenna switch that lets you select two coax lines and/or random wires (direct or through tuner), balanced line and external dummy load. The MFJ TrueCurrentBalun for balanced lines minimizes feedline radiation that causes field pattern distortion, TVI and RF in you shack. Ceramic feedthru insulators for balanced lines withstand high voltages and temperatures.Replacing two variable capacitors with a single differential capacitor gives a wide range T-Network tuner with only two controls -- a tuning capacitor and a roller inductor. Simple 2-knob tuning makes tuning easier than ever. You get minimum SWR at only one setting with a broadband response that ends constant re-tuning. You'll spend your time QSO'ing instead of fooling with your tuner. The compact cabinet has plenty of room to mount the roller inductor away from metal surfaces for highest Q -- you get high efficiency and more power into your antenna.Wide-spaced tuning capacitor plates let you run high power without arcing. MFJ's lighted Cross-Needle Meter shows you SWR, forward and reflected power simultaneously. It reads peak or average power on 2000 or 200 Watt ranges. The lamp has on/off switch and uses 12 VDC or 110 VAC with MFJ-1312D.Most tuners use a voltage balun that forces equal voltages on the two antenna halves. It minimizes unbalanced currents only if the antenna is perfectly balanced -- not the case with practical antennas. The MFJ-986 uses a true current balun to force equal currents in the two antenna halves -- even if the antenna is not perfectly balanced! The MFJ TrueCurrentBalun gives superior balance over voltage baluns and minimizes unbalanced current. This reduces field pattern distortion, concentrates your power for a stronger signal plus it reduces TVI and RF in your shack caused by feedline radiation.
When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away. Jim Gifford, KM4MPF.
