Short 85 foot long dual band 80/40 Meter dipole antenna is full-size on 40 Meters and has ultra-efficient end-loading on 80 Meters. Handles 1500 Watts. Super-strong injection-molded center insulator with built-in SO-239 connector and hang hole. Solderless, crimped construction. 7-strand, #14 gauge hard copper antenna wire. Connect your coax feedline directly, no tuner needed.
Each side of the dipole is broken up by a coil that presents a high impedance at 40 meters and acts as a loading coil on 80 meters, allowing the antenna to resonate on 80 meters even though it is physically shorter than a half-wavelength (approximately 130 feet at 3.7 MHz).
Because this antenna acts as a dipole on both bands its impedance is around 50 to 70 ohms, permitting it to be fed with coaxial cable. The use of a current balun between the coaxial feedline and the antenna is highly
recommended, to help prevent stray RF from traveling down the coaxial cable’s outer shield.
