Introduction
The Rapid Deployment Tuned Dipole Antenna frequency labels to indicateWire has
tuned lengths. For operation, each side of the antenna is unwound to the tuned
length for the frequency required. he label should be level with the end of theT
winder as shown in the picture below. Lengths for intermediate 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 operate continuously across the band from 2-30 z. The power rating is 150MH
W . can be used in a number of congurations , depending onPEP It (see over)
structures available for elevation. Compatible Barrett masts include, 10m Rapid
Deployment Mast (P/N 2090-02-21), 10m Rapid Deployment Composite Mast (P/N
2090-02-24) and 5m Rapid Deployment Mast (P/N
2090-02-04). This antenna is most suitable for HF
radio manpack and temporary base station
deployment. This guide will indicate the
recommended deployment type for each

Horizontal Configuration
Inverted V Configuration
H congurationorizontal has maximum
gain on the broadsides of the antenna
and reduced gain along the axis. Therefore, the broadsides should point in the
direction of the receiving stations, if possible. Antenna height above ground
affects radiation angle. Lower heights give higher radiation angle betterwhich is
for (short distance) . heights give lower radiationNVIS er operation Greater a
angle, for long distance communication.which is favourable er
The inverted-V has a moreconguration
omni-directional pattern than the
h congurationorizontal , with lower maximum gain. The ends of the antenna
should be at least 0.5m above ground. Suitable mainly for and mediumNVIS

Sloping Configuration
Single Ended Configuration
Radiation with the Sloping becomes more directional, withconguration
increased gain in the direction of the lower end of the antenna, and reduced gain
towards the higher end.
For rapid deployment, with reduced but still acceptable efciency, the antenna
can be operated single ended. In this conguration, one side of the antenna is
unwound to the desired frequency and tied to an elevated structure. The central
balun should be located close to the ground, and the remaining
side of the antenna (“earth”) partly unwound (5 to 10m) and
stretched out on the ground below the radiating element.
