VERTICAL GROUND PLANE ANTENNA 27 to 50 MHz
The "DISPATCHER", DP-275 ULBB
The ULBB Uni-Linear Vertical ground plane antenna, the DP-275 Dispatcher, is a vertical
ground plane antenna with an exceptionally low angle of radiation and is designed and
manufactured to fulfill the exact antenna requirements for commercial or citizens band "CB"
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 snow 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.
