Used Very Good HyGain SPT500 SN67166. Includes every piece of hardware and antenna.
Hy-Gain 10/12m Super Penetrator Vertical Antenna
5.3dB gain, 22ft tall, radials are 8'-9" long, accepts mast 1-1/4" to 1-5/8" in diameter.Rated to survive winds up to 80mph.
This fantastic true full-size 5/8 Wave 10 / 12 Meter vertical antenna from Hy-Gain was a legend in the 70’s . . . now it’s back to prove its legendary status once again!
A Full-size radiator with lower radiation angle concentrates power closer to the ground, where you want it. Measures 22 foot, 9.5 inches. Larger diameter, heavy wall ply-tubular construction makes the new Super-Penetrator™ the absolute top omnidirectional antenna around! Four full-length radials and special machine-formed brackets give extra talk-power and overall strength.
Electrical performance has been increased to a new standard by the use of a longer radiator and double-matching tuning with linear phasing techniques that provide low SWR and more radiated energy. The double-matching also provides a DC path to ground to drain off precipitation static, giving an extremely low noise antenna capable of high power.
SPT-500 is specifically designed to accept AM-FM-SSB-DSB signals with low loss. Handles 1.5 killowatts. This antenna is illegal for 11 Meters use.
