Alpha Antenna HF Base HD Antenna

The Heavy Duty (HD) 10–80 Meter HF Base Antenna is built for rugged, permanent outdoor deployments, delivering reliable performance across a wide frequency range of 3.5 MHz to 30 MHz. Designed to withstand challenging environments, this robust system features a self-supporting telescopic vertical element constructed from six 3-foot sections with stainless steel clamps, ensuring durability and easy setup. Its versatility makes it ideal for amateur radio operators seeking efficient multi-band communication from 10 to 80 meters.

This antenna includes everything you need for seamless operation: a wire NVIS element for enhanced local coverage, a grounded counterpoise wire, and a ground stake to complete the circuit—eliminating the need for additional radials. The integrated matching network enables fine-tuned resonance on 10, 20, 40, and harmonically enabled bands like 15 meters, as well as 12 and 17 meters. Whether you're working DX or engaging in NVIS communication, this system ensures a balanced, efficient signal for a variety of operating modes.

Built with heavy-duty materials, this HF vertical base antenna is designed for consistent performance in permanent installations. Its off-center-fed dipole-like configuration, combined with a grounded counterpoise, provides robust signal reception and transmission while minimizing noise. Whether you’re an avid DXer or rely on NVIS for emergency communication, the HD 10–80 Meter Base Antenna offers the durability and versatility you need for reliable operation year-round.
