® assuredcommunications™ RF-397 VEHICULAR UHF ANTENNA The Harris RF-397 Vehicular UHF Antenna is a broadband, center-fed antenna operating in the 225 to 420 MHz frequency range. It maintains a VSWR of less than 3.0:1 over the entire frequency range without the need for a tuner or band switching. The RF-397 is efficient and built ruggedly, providing economical and dependable communications. The RF-397 Antenna is designed to meet requirements of the Harris Falcon® II series UHF vehicular transceivers and is compatible with other Harris multiband transceivers as well. Covering only the UHF band allows the antenna to be very efficient while maintaining a very low profile of less than one meter. The Type N connector is below the base with a nominal impedance of 50 ohms. Continuous power capability is 60 watts. It is completely compatible with present NATO mounting schemes and communication systems. The RF-397 is intended primarily for ground vehicular applications but can be adapted for shipboard and fixed-station installations. The low profile design allows the vehicle to remain hidden until the entire vehicle is visible. Specifications for the RF-397 General Mechanical ■ Frequency Range: 225 to 420 MHz ■ Height: 33.5 in.
