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
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.
