The QEL-ST-2-18-N-SG-R from Steatite Antennas is a Cylindrical Paraboloid Direction Finding Antenna that operates from 2 to 18 GHz. This horizontally/vertically or ±45°-polarized antenna provides a gain of 13-24 dBi and has a VSWR of less than 2.5:1. It is mounted on a high-speed rotating direct drive positioner that rotates at a speed of less than 200 rpm and includes mechanisms for complex scan control. This antenna has an azimuth beamwidth from 4° to 30° and an elevation beamwidth from 20° to 35°. It is available in a transparent, low-loss radome enclosure and is ideal for ELINT applications.
