Applications:

The HT-20 is a lightweight transportable HF antenna that provides excellent radiation characteristics for short range 0 to 300 mile circuits. The lightweight rugged design and quick erection features are ideal for meeting rapid deployment requirements. The installed geometry minimizes land area usage and permits installation in the space constraints typically encountered in an operational area.

Features:

The key to the transportable design is the lightweight telescoping mast which collapses to a transport length of 63 inches for ease of storage and handling.

Characteristics:

The primary mode of propagation is HF Near Vertical Incident Skywave (NVIS) with the maximum radiation directed toward the zenith. The antenna provides broadband operation in the 2-30 Mhz frequency range with a maximum VSWR of 2:1. The 50 ohm input impedance is achieved by a mast-top mounted balun feeding the dipole elements. The antenna is rated at 1 kW average, 2 kW PEP input power.

Equipment Supplied:

Equipment supplied includes the telescoping mast, element wires, balun, terminations, accessory kit and canvas carrying bag.

Optional Equipment:

Transit case.
