MFJ KW Differential-T TM Antenna Tuner . . . Gives you absolute minimum SWR . . . Simple 2-knob tuning . . . Lighted Cross-Needle SWR/Wattmeter . . . AirCore TM Roller Inductor . . . 6-position antenna switch . . . Balun for balanced lines . . . 1.8-30 MHz coverage MFJs innovative Differential-T TM tuner uses a differential capacitor that makes tuning easier than ever. Gives minimum SWR at only one setting. Broadband design ends constant retuning. The MFJ-986 is a rugged roller inductor antenna tuner that handles 3 KW PEP SSB amplifier input power (1500 Watts PEP SSB output power). Tunes 1.8-30 MHz continuously, including MARS and all the WARC bands. MFJs exclusive AirCore TM 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 retune your frequency. A lighted peak and average reading crossneedle 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 TM for balanced lines minimizes feedline radiation that causes field pattern distortion, TVI and RF in your shack. Ceramic feedthru insulators for balanced lines withstand high voltages and temperatures. Differential-T Tuner TM . . . . A new twist on proven technology Replacing two variable capacitors with a single differential capacitor gives wide range T-network tuning with just 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 and a broadband response that ends constant retuning. Youll spend your time QSOing instead of fooling with your tuner. The compact 10 3/4x4 1/2x15 inch 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. Lighted cross-needle meter MFJs lighted Cross-Needle Meter shows you SWR, forward and reflected power simultaneously. It reads peak or average power on 2000 or 200 Watt ranges. Lamp has on/off switch and uses 12 VDC or 110 VAC with MFJ-1312D, $14.95. MFJ TrueCurrentBalun TM reduces feedline radiation 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 TM 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. No Matter What TM Waranty Protected by one year limited warranty. Call your dealer for your best price! In stock at ham dealers everywhere.
