The DPV-40B Antenna consists of two vertically polarized omnidirectional dipole antennas, each covering the frequency range of 100-156 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 2-1/2 inch IPS pipe, enclosing the electrical connections away from the environment.
