The QEL-ST-0.5-18-N-SG from Steatite Antennas is a direction finding and omnidirectional high performance spinning antenna sub-system that operates from 0.5 to 18 GHz. The antenna is mounted on high speed rotating direct drive positioner with complex scan control and is housed in RF-transparent, low-loss radomes. Cylindrical paraboloid reflectors are used to provide a narrow azimuth beamwidth with broad elevation coverage. The antenna delivers a gain of up to 22.1 dBi and has a 45° slant linear polarization. It is ideal for ELINT, EW, and spectrum management antenna applications.
