The MFJ 1984
full HF coverage antenna is available in two versions: max. 300 W (MP) and max. 800 W (HP) SSB.
End-Fed Horizontal Wires (EFHW) cover multiple bands with-out traps, stubs, or resonators. End-fed radiators have the unique quality of resonating on the 1/2-wave fundamental frequency plus odd/even harmonics above! No tuner needed on most frequencies.
No long counterpoise, radials or feedline required. Rugged weather-resistant 50-Ohm matching network. Stainless Steel Hardware and UV resistant materials
