Additional Product Info



The DPV-63A is a militarized, omnidirectional, transportable UHF antenna designed to be stackable for use in air to ground applications. The antenna is vertically polarized with an instantaneous bandwidth of 225 to 400 Mhz, is omnidirectional within +/- 1 dB and has a 14 degree nominal beam uptilt. The antenna may be shelter mounted, tower mounted or ground mounted using guys and a 6 foot pedestal. The lightweight, quick-erect, rugged design makes the DPV-63A ideal for rapid deployment requirements for UHF communications.


The DPV-63A is a stacked dipole element array. The overall height is 8.25 feet, a dual stack is 16.5 feet, and a triple stack is 24.75 feet in height. When stacked, there is 28 dB of isolation between the stacked antennas. The antenna is supplied with a pivot base that permits ease of assembly and erection for either shelter or ground mounted configurations. The base provides captive for shelter mounting and a fold away ground anchor to prevent slipping during installations on most types of ground. Guys, anchors, grounding rod and strap are available for ground mounts. Also available for ground mounting is a 6 feet tall pedestal to elevate the antenna above ground. Typical installation times for a single DPV-63A are less than 10 minutes for a shelter installation using one person, and less than 10 minutes for a ground installation using two people. Installation typically increases 5 minutes for each stack added. The military nomenclature of the antenna is AS-3977.

Optional Equipment:

Band pass filter, 6 ft ground mount pedestal, guys, anchors, ground rod, ground strap.
