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.
