High Gain Omni Vehicular Multi-Band Communications Antenna System UHF/L-Band.
Description:
The FIRST RF Corporation FRF-172 antenna system is an omni-directional, high power, multi-band, high gain omni UHF/L-Band antenna system suitable for installation on commercial and tactical wheeled vehicles.
The antenna eliminates the need for separate UHF and L-Band antennas on vehicles and improves cosite and RF system performance.
The antenna is available in a ruggedized spring mount currently as a dual band (UHF/L) with optional tri-band upcoming release which includes VHF.
The product is the latest version of the FIRST RF multi-band vehicular family of antennas which have been manufactured in high quantities.
The antenna has been designed to meet MIL-STD 810 environments and to pass additional Munson road test conditions when suitably mounted on the vehicle platform. The antenna has also passed oak beam strike testing at 25 mph.
