The DPV-51XN antenna consists of two vertically polarized, omnidirectional, dipoles fed in phase, covering the frequency range 225 to 450 MHz. These dipoles are sealed in a single fiberglass radome that provides both mechanical stability and environmental protection. The antenna is designed for ground-to-air communication and use in an extreme environment. It is provided with a coaxial mounting arrangement to enclose the electrical connections away from the environment. The base mounting consists of a 5.81 inch diameter base with four .438 inch diameter holes on a 4.50 inch diameter circle. The element has threaded connector to allow removal for transport purposes.
