Hy-Gain SPT-500 Super Penetrator HF Vertical Antennas
These true full size 5/8 wave, 10/12 meter Hy-Gain SPT-500 Vertical Antennas 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 horizon… where you want it. SPT-500 antennas measure 22 ft., 9.5 in. high with large diameter, heavy-wall tubular construction that puts the new SPT-500 Super Penetrators among 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. Double-matching also provides a DC path to ground to drain off precipitation static, resulting in extremely low-noise antennas capable of high power.
SPT-500 antennas are specifically designed to accept up to 1.5 kilowatts with low loss. Order your Hy-Gain SPT-500 Vertical Antennas from DX Engineering!
