MFJ-17754 40/20M Dipole Antennas are shortened, coaxial-fed, 42 ft. long dual-band resonant antennas. While functioning as a full-size dipole on 20-meters, it’s also an ultra-efficient end-loaded dipole on 40-meters. You may operate these dipoles at up to 1,500 watts!
Featuring a super-strong, injection-molded center insulator with a built-in SO-239 connector, these solderless, crimped, 7-strand, 14-gauge hard-copper wire antennas may be connected to your coaxial feedline directly, with no antenna tuner needed. Each side of the dipole is made resonant by a coil that presents a high impedance at 20-meters and acts as a loading coil on 40-meters. This allows the antenna to resonate on 40 meters, even though it is physically shorter than a 40-meter half-wavelength.
