COTS and custom designed 0.5 to 40 GHz direction finding and omni-directional high performance spinning antenna subsystems.
ELINT antennas are used to intercept RF signals and often form part of a larger subsystem.
Our ELINT spinning Direction Finding antennas are mounted on high-speed rotating direct-drive positioners with complex scan control, housed in RF-transparent, low-loss radomes. Cylindrical paraboloid reflectors are used, which provide a narrow azimuth beamwidth with broad elevation coverage.
Our COTS ELINT antennas cover ranges from 0.5 to 40 GHz and our specialist antenna designers can produce bespoke Electrical Intelligence solutions for a range of ELINT, EW and Spectrum Management applications.
