The RF-1944-AT020 antenna
is a lightweight, portable broadband
dipole antenna providing 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
support instantaneous bandwidth
performance over the entire
1.6 to 30 MHz frequency range.
The RF-1944-020 is very effective
for operations employing agile
waveforms such as ALE and
frequency hopping.
