Introduction
The Barrett Rapid Deployment Broadband Dipole Antenna is a dipole antenna with
loading to allow broadband operation. It will operate continuously across the
band from 2-30 MHz. The power rating is 150 W PEP. Throwing cords are provided
that can be used to elevate the antenna or to secure it to the ground. The
antenna can be used in a number of configurations (see over), depending on the
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 configuration with these symbols.

Horizontal Configuration
Horizontal configuration has a 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 angles which is
better for NVIS (shorter distance) operation. Greater heights give a lower
radiation angle, which is favorable for longer distance
communication.
Inverted V Configuration
The inverted-V configuration has a more Omnidirectional pattern than the
horizontal configuration, with lower maximum gain. The ends of the antenna
should be at least 0.5m above ground. Suitable mainly for NVIS and medium-
distance communication.
Sloping Configuration
Radiation with the Sloping configuration becomes more directional, with
increased gain in the direction of the lower end of the antenna, and reduced
gain towards the higher end.
Inverted U Configuration
The inverted U configuration has a radiation pattern between that of a
horizontal configuration and an inverted V configuration. For optimum
performance, the radiating elements should be fully unwound, and should not
touch the ground. Suitable for NVIS to medium distance. Longer distance
performance will be enhanced by erecting the antenna at a height of 10m or
more.
