1/2

The RF-1944-AT020 antenna is a lightweight, manportable

broadband dipole antenna that provides radiation patterns ideal

for HF skywave communications from 0 to 500 miles. The rugged,

yet simple design allows quick installation into its primary Inverted

Vee configuration. The termination loads provide instantaneous

bandwidth performance over the entire 1.6 to 30 MHz frequency

range. The RF-1944-AT020 antenna is an excellent choice when

operating with frequency agile waveforms such as ALE and

frequency hopping. The antenna does not require tuning by the

transceiver antenna coupler.

The RF-1944-AT020 is used for up to 20 watts and weights less

than four pounds (1.8 kg). The antenna is comprised of a balun,

two radiating elements with integral terminating loads, two

ground stakes, a coaxial cable, a weighted throwing line, and a

carrying bag. The coaxial cable has male BNC connectors for direct

attachment to the balun. The RF-1944 AT020 antenna does not

include a mast.
