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 (150...
These are manual tuners designed to tune small loop antennas and are particularly useful for antenna restricted and/or portable operation. There are three models of loop tuners available: The MFJ-933B, MFJ-935B, and MFJ-936B. The actual loop-tuner circuitry is identical in the three tuners....
