Multifunction Multiband Antenna Technology: FRF-105, 115, 119 Series Omni and Directional Antennas for Commercial, Tactical Ground Vehicles and Fixed Site Applications


Multi-decade broadband antennas represent FIRST RF's signature product line. They are well suited for communications, EW, Metrology, EM Surveilance, and Sprectrum Monitoring. Demonstrated under an Army Phase II SBIR contract, the multi-decade antenna technology became the first antenna that can be designated as the Army "Common Antenna" cabable of performing multiple communications and electronic warfare (EW) functions critical in the Global War on Terror. The FIRST RF "stackable" antenna technology covers an unprecedented wideband frequency span and can provide omni, directional and steerable antenna patterns from a single antenna structure

The FIRST RF Corporation FRF-105, 115, 119 series of antenna systems comprise omni, directional, high power, multi-band and multi-function antennas into a rugged integrated antenna suite suitable for installation on commercial and tactical wheeled vehicles as well as fixed site applications.

The series of 105, 115 and 119 antenna systems eliminate the need for separate single band antennas on vehicles, towers, or buildings and improves cosite and RF system performance.

The antennas are available in a ruggedized spring mount and can be provided with kits that include risers, cables, mounting brackets and fasteners for varying installation requirements.

The product line of 105, 115 and 119 series antennas have been manufactured in high quantities with over 165,000 delivered since 2005.

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.
