DPV-51M
|
|
Applications:
The DPV-51M UHF antenna consists of two vertically polarized, omnidirectional dipoles fed in-phase, covering the frequency range of 225-400 Mhz. The dipole array is sealed in a fiberglass radome that provides both mechanical stability and environmental protection. The antenna is designed for ground-to-air communications in an extreme environment. It is provided with a coaxial mounting arrangement to enclose the electrical connections away from the environment. Features: The antenna is ruggedly built, yet lightweight, making it very mobile. The antenna is fabricated with a spring base that enables the antenna to survive impacts with brush or low power lines. It is completely preassembled for shipment and installation. The installation interface is a 4.50 inch diameter bolt circle. |
