Alpha Antenna 4 Element Radial Kits
Alpha Antenna 4 Element Radial Kits are used to enhance many of Alpha Antenna's portable antennas. Featuring a hub that attaches either to the top or bottom (depending on desired radiation pattern) along with four 35-foot long wire elements that are attached the center hub with four stakes at the ends. This allows for easy deployment and takedown. The clip attaches to the ground post on the AutoMatch and is what connects the elements to the antenna system. Additional Feature and Specifications: Includes: • 4 – 35 foot HF Elements • 1 – Clip • 1 – Adapter Hub • 4 – Stakes • 4 – Carabiners

Alpha Antenna ProMaster Heavy Duty HF Base Vertical Antennas
Alpha Antenna Heavy Duty HF Base Vertical Antennas are designed for permanent outdoor installations covering the 80 through 10-meter Amateur bands. They operate as a full wavelength on 10 meters, half wavelength on 20 meters, and quarter wavelength on 40 meters. The antenna also supports 15 meters as it is the third harmonic of 40 meters. Additional tuning for resonance on 12 and 17 meters is achieved through the included matching network. This antenna system includes a grounded counterpoise element and ground stake, (no radials in addition to this are required). The combination of these components makes this antenna system function like an OCF (off-center fed) Dipole.

Alpha Antenna Low Profile Lite HF Base Vertical Antennas
Alpha Antenna Low Profile Lite HF Base Vertical Antennas cover the 10 to 80 meters amateur bands and are considered the 'lite' version of the ProMaster Heavy Duty HF Base Vertical Antenna. This antenna system features an easy-to-deploy telescopic stainless-steel whip, which can be retracted when winds of more than 50MPH are expected. The total length of the 17.75ft. vertical whip and the 25.25ft. horizontally sloped element equals the magic number of 43ft., a length used by many excellent systems for multi-band HF antenna operation from 80 to 10 meters. The last element is an 8ft. grounded counterpoise wire, which completes the circuit by creating a static drain for noise, making it easier to hear other stations.
