Alpha Antenna HF Mobile EmComm antenna

The Alpha HF Mobile Antenna is a rugged and versatile solution for mobile HF communications, covering 6 to 40 meters with ease. Designed for simplicity and efficiency, this antenna eliminates the need for changing whips or making physical adjustments to switch bands. With no external power or control interface required, it works seamlessly with an external tuner to provide reliable performance across all supported frequencies. Compact and lightweight at 32 ounces, this antenna is perfect for amateur radio operators seeking an efficient mobile setup.

The antenna includes a 5-foot stainless steel whip with a durable ferrule and a Black AutoMatch unit featuring a 3/8 24 mounting bolt and an SO239 connector. Its design ensures quick installation and optimal performance when mounted high on a vehicle with proper grounding. The Alpha HF Mobile Antenna supports power ratings of 100W PEP SSB, 50W CW, and 10W for digital, FM, or AM modes, making it suitable for a wide range of communication needs. Its rugged construction ensures durability in various conditions, with a deployed length of 5′ 5″.

To achieve the best performance, proper installation is essential. Mounting the antenna as high as possible on a metal surface and avoiding parallel placement with the vehicle’s frame ensures effective grounding and signal transmission. While a direct surface mount is recommended, the antenna can be used with a Tri-Magnetic Mount for added flexibility, though some modifications may be required. This antenna is particularly effective for making regional and DX contacts on 6 to 20 meters, while also providing decent results on 30 and 40 meters. Whether used for mobile operations or emergency communications, the Alpha HF Mobile Antenna offers robust performance and unmatched versatility.
