These fantastic true full size 5/8 wave, 10/12 meter SPT-500 vertical antennas from Hy-Gain were a legend in the '70s--now they're back to claim that status once again! A full size radiator with a lower radiation angle concentrates power closer to the ground, where you want it. The SPT-500 antennas measure 22 ft., 9.5 in. high with larger diameter, heavy-wall ply-tubular construction that makes the new Super Penetrators one of the top omnidirectional antennas around! Four full-length radials and special machine-formed brackets give extra talk power and overall strength. Electrical performance has set a new standard with the use of a longer radiator and double-matching tuning with linear phasing techniques that provide a low SWR and more radiated energy. The double-matching also provides a DC path to ground to drain off precipitation static, resulting in extremely low-noise antennas capable of high power. Hy-Gain SPT-500 Super Penetrators are specifically designed to accept AM-FM-SSB-DSB signals with low loss. They handle 1.5 kilowatts.
