The DPV-37 antenna consists of two vertically polarized, omni-directional, dipole antennas, each covering the frequency range of 225 to 400 MHz. The dipole elements are mounted one above the other on a common axis. 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 mount atop a 1 ¼ inch or 2 ½ inch IPS pipe, shielding the electrical connections away from the environment.
