BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION
Tactical Tuned Wire Dipole Antenna (2090-02-01)
The Tactical Tuned Dipole Antenna is a tuned
antenna with frequency labels to indicate
tuned lengths. For operation, each side of
the antenna is unwound to the tuned length
for the frequency required. For operation at
a labelled frequency, the label should be
level with the end of the winder as shown
in the picture below. Lengths for interme-
diate frequencies should be estimated and
tied off appropriately. The remaining wire
remains on the winder. The throwing cord
can then be used to elevate the antenna.
The antenna will handle 100 W continuous
data and CW transmission. The antenna
can be used in a number of configurations,
depending on structures available for eleva-
tion.

Tactical Tuned Wire Dipole Antenna Configurations
Horizontal Dipole
The horizontal dipole has maximum gain on the broadsides of the antenna,
and reduced gain along the axis. Height above ground affects radiation angle.
Lower heights give higher angle radiation, better for NVIS (short distance).
Higher heights give lower radiation angle, better for long distance communi-
cation.
