Alpha Antenna 10-80M & Marine Promaster HF Base Antenna Tuner Free

Alpha Antenna 10-80M Marine ProMaster HF Base Antenna – Tuner Free

The Alpha Antenna ProMaster is a high-performance multi-band HF base antenna designed for amateur radio, marine HF and emergency communications where space is limited but reliable coverage is essential. Covering 80 through 10 metres without the need for an external tuner in many installations, the ProMaster combines vertical DX performance with NVIS capability for dependable short and long-distance communication.

This innovative balanced antenna system uses a self-supporting telescopic vertical radiator together with a horizontal NVIS wire element and grounded counterpoise to maximise effective radiated power while maintaining a low SWR across the HF spectrum. The result is excellent all-round performance for SSB, CW, AM, digital modes and ALE operation.

Designed for permanent or transportable use, the ProMaster is quick to install and can be mounted approximately 5 to 7 feet above ground level on conductive or non-conductive supports. The weatherproof outdoor NEMA enclosure houses the transformer and SO-239 feed connection for dependable long-term outdoor use.
