GROUND PLANE ANTENNAS


VERTICAL GROUND PLANE ANTENNA 27 to 50 MHz

The "DISPATCHER", DP-275

The DP-275 Dispatcher is a 5/8 wave vertical ground plane antenna with an exceptionally low angle of radiation and is designed and manufactured to fulfill the exact antenna requirements for commercial communications. It incorporates a shunt match feed with 50 ohm impedance rated to 1,000 watts and a nominal 1.5 or less VSWR at the resonant frequency. The Mosley "DP-275" offers a 3.4 gain over a standard ground plane antenna. This antenna is grounded for lightning protection which also reduces rain and snowDP-275 Details... Click Me! static.

6063-T832 aluminum alloy tubing with high tensile strength makes this antenna the durable antenna desired for commercial use. The vertical element of this DP-275 telescopes into a wrapped phenolic base tube which has a greater strength than the aluminum element. Radials (horizontal elements) terminate into a high strength "cycolac" base which has again, more strength than the aluminum element.

Antenna mounting is simplified: just mount the antenna on a mast, tighten two screws, and lock nuts. All hardware is of stainless steel or steel-plated to meet government specifications.

This vertical ground plane has swaged (tapering ends of aluminum tubing) designed to reduce wind load and any possibility of vibrations which could cause metal fatigue.

When ordering the DP-275, please indicate the frequency and power required.
