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 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.
