Cosite Series Vertical Dipole VHF and UHF Antennas  

Photograph

The DPV-94 is a VHF dipole operating over the frequency range of 30-108 MHz with a 3:1 VSWR and handles 125 watts of RF average power.

The DPV-93 consists of the same dipole as the DPV-94 along with a VHF hybrid and antenna simulator to provide two RF ports with a minimum isolation of -20 dB between the ports. This arrangement accommodates either 2 independent 125 watt radios or else one 250 watt radio and a receiver.

The DPV-96 is a VHF dipole as in the DPV-94 but also includes a 225-500 MHz UHF antenna above the VHF dipole. The UHF dipole handles 50 watts average of RF power.

The DPV-95 contains both the VHF and UHF dipoles of the DPV-96 and also includes the VHF hybrid and antenna simulator of the DPV-93.

These antennas are designed for vehicular mounting and have been tested to severe environmental requirements. These antennas are designed to handle unique cosite system problems.
