Fixed-station shortwave Broadband Whip Antenna
Product Overview
The Fixed-Station Shortwave Broadband Whip Antenna adopts naval antenna technology, featuring no tuning required, self-supporting structure, excellent performance, and durable reliability. The antenna is fed using a λ/4 tapered matching method, with frequency-divided matching networks designed at the middle and top of the elements, resulting in radiation efficiency far superior to resistive-loaded or heat-dissipative antennas of the same type. The outer surface of the elements is covered with high-strength fiberglass composite radome, preventing exposure of connected metal components. It is suitable for coastal areas, rooftops, and harsh environments. This antenna is an ideal matching antenna for shortwave transceivers up to 2 kW.
