Alpha Antenna DuoPole Military Vertical Antennas are stated to provide up to 1500 miles of digital mode coverage within the 7-30MHz range and up to 60 miles of all-mode coverage (depending on height) across 1.8-7MHz, 7-30MHz, and 144/220/430MHz frequencies. Compact and lightweight, the Alpha Antenna DuoPole stands at just 36 inches tall and weighs only 22 ounces. These antennas are suitable for low power Amateur SSB, CW and Digital modes and compatible with digital quantum and spread-spectrum equipment, supporting both singular and simultaneous frequencies for Ground-wave and Skywave communications

Key Features and Specifications

Frequency Range: Provides up to 1500 miles of digital mode coverage within the 7-30MHz range and up to 60 miles of all-mode coverage (depending on height) across 1.8-7MHz, 7-30MHz, and 144/220/430MHz.

• Compact Design: Measuring only (WHD) 4.0 x 36.0 x 1.5in. and weighing only 22oz., these antennas are highly portable and easy to deploy.

• Durability: Features an SO-239 coaxial connector, and built to withstand harsh conditions, ideal for field and emergency operations.

• Low Noise Reception: Designed to minimize noise, ensuring clear and reliable signal reception.

• Digital Mode Compatibility: Amateur digital modes and compatible with digital quantum and spread-spectrum equipment, supporting both singular and simultaneous frequencies for Ground-wave and Skywave communications.

• Power Rating: Requires a minimum digital input signal of 5W with a maximum input power of 30W for digital modes. Includes support for MIL-STD-188 M110a digital communications mode, rated at 25W continuous with bursts of 100W digital for up to 1 minute using the MIL-STD Data Modem Terminal (MS-DMT) and Automated Message Terminal (AMT) software applications.

Deployment:

1) Mount the DuoPole antenna on a Male 3/8- 24in. stud with exposed threads no longer than 19mm (0.75in.).

2) Attach a feed line to the SO-239 on the antenna and connect the other end to your tuner/equipment.
