  • Notes
  • The MFJ-986 Differential-T 3kW Tuner uses a differential capacitor to make tuning easy. It continuously tunes all frequency from 1.8 trought 30 MHz, including all the WARC bands. The roller inductor lets you tune down SWR to the absolute minimum. The MFJ-986 also features a peak reading cross-needle, SWR/Wattmeter, and a new current balun that will work with balanced open wire, twinlead, or twin-axial feedlines. An internal six position antenna-selector switch selects two coaxial line output, a single wire line-balanced line output, or an external dummy load connection.
