10-80M HF Base Antenna, ProMaster LT – Alpha Antenna

Lightweight 10-80 Meter HF Base Antenna

The Alpha Antenna ProMaster LT is a vertically-oriented base antenna spanning 10 to 80 meters of HF frequency coverage. The system combines a telescopic 17-foot 9-inch vertical element with a 25-foot 3-inch horizontal wire configuration, totalling approximately 43 feet — a proven dimension for multiband HF operation.

The antenna features an integrated Auto Match tuner housed in an IP-65 rated enclosure, along with an 8-foot grounded counterpoise element that functions as a static drain. The design delivers strong DX and NVIS performance in a compact package suitable for amateur radio and emergency communications. The vertical element retracts for wind conditions exceeding 50 mph.
