The AN/FRD-10 is a United States Navy circularly disposed antenna array (CDAA), built at a number of locations during the Cold War for high frequency radio direction finding and signals intelligence. In the Joint Electronics Type Designation System , FRD stands for fixed ground, radio, direction finding. 14 sites were originally constructed as ...
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS ...
Corner reflector antennas have moderate gain of 10–15 dB, [2] high front-to-back ratio of 20–30 dB, and wide bandwidth. Corner reflector antennas are widely used for UHF television receiving antennas , point-to-point communication links and data links for wireless WANs , and amateur radio antennas on the 144, 420, and 1296 MHz bands.

The antenna array is composed of three concentric rings of antenna elements. Each ring of elements receives RF signals for an assigned portion of the 1.5 to 30-MHz radio spectrum. The outer ring normally covers the 2 to 6-MHz range (band A), but also provides reduced coverage down to 1.5 MHz.
Q-par Angus was a designer and manufacturer of microwave and RF antennas for commercial and defense use; in May 2013 the company was acquired by Solid State PLC. [ 1 ] The company was formed in 1973 in Birmingham, UK, by Dr Richard Holliday and his wife Jenny Holliday.
AN/ALQ-99E – The version mounted on the EF-111A, a heavily modified variant of the F-111A introduced in 1977. The jamming equipment was mostly stored on the underside of the aircraft in the bomb bay, while the receiving equipment was mounted to the vertical stabilizer, similarly to the EA-6B. It featured a 70% commonality with the AN/ALQ-99F ...
