Introduction

The Rapid Deployment Tuned Wire Dipole Antenna has frequency labels to indicate tuned lengths. For operation, each side of the antenna is unwound to the tuned length for the frequency required. The label should be level with the end of the 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 MHz. The power rating is 150 W PEP. It can be used in a number of configurations (see over), depending on 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 angle which is better for NVIS (shorter distance) operation. Greater heights give a lower radiation angle, which is favorable for longer distance communication .BARRETT-PN-2090-02-01-Rapid-deployment-dipole-D-Tunable-Wired-HF-Antenna--

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 confguration becomes more directional, with increased gain in the direction of the lower end of the antenna, and reduced gain towards the higher end.

Single Ended Configuration

For rapid deployment, with reduced but still acceptable effciency, the antenna can be operated single-ended. In this confguration, 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.
