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...

At that time I'd just changed my antenna at home from a trapped dipole into a dipole without traps. I had also re-equipped the mast system with high quality coaxial cable. Chatting to John G3BDQ led to the advice that I should install a balanced feeder to get a reduction in received...
