The RF-1944 antenna series includes
lightweight, transportable broadband
dipole antennas providing radiation
patterns ideal for HF skywave
communications from 0 to 1500
miles. Their rugged, yet simple
design allows quick installation
into the primary Inverted Vee
configuration. Termination loads
provide instantaneous bandwidth
performance over the entire 1.6
to 30 MHz frequency range. The
antennas do not require an antenna
coupler, making them ideal for
operations with frequency-agile
waveforms. The RF-1944 series
operate at two different power
levels: the RF-1944-AT150 up to
1
2
150 Watts and the RF-1944-AT400
up to 400 Watts. Both antennas
include a balun, two dipole radiating
5
elements, two terminating loads,
two ground rods, two ground stakes,
