For example, a PAR16 lamp is approximately 2 inches or 50.8 mm in diameter. [1] The size of rectangular PAR lamps is expressed as the letters REC followed by the reflector's mouth height, the letter "X", and the reflector's mouth width—with both dimensions in millimeters. For example, REC142X200 lamps are 142 high and 200 mm wide. [2] [3]
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.
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 ...
For directional antennas, the Yagi antenna is the most widely used as a high gain or "beam" antenna. For television reception, the Yagi is used, as well as the log-periodic antenna due to its wider bandwidth. Helical and turnstile antennas are used for satellite communication since they employ circular polarization.
The F-10 was used as a radar testbed to develop the APQ-72 radar. The nose of an F-4 Phantom was added to the front of an F-10B. Another F-10 had a modified radome installed by the radar manufacturer Westinghouse. Yet another TF-10B was modified with the nose from an A-4 Skyhawk. [49] In 1968, three Skyknights were transferred to the U.S. Army.
The ADF may be used to home in on a station. Homing is flying the aircraft on the heading required to keep the needle pointing directly to the 0° (straight ahead) position. To home into a station, tune the station, identify the Morse code signal, then turn the aircraft to bring the ADF azimuth needle to the 0° position.
The array is centered on a ground screen 1,443 feet (439.8 m) in diameter. The arrangement permits accurate direction finding of signals from up to 4000 nautical miles (7408 km) away. AN/FLR-9 antenna array at Misawa Air Base c. 1980. FLR-9s were constructed at the following places: [3] USASA Field Station Augsburg (Gablingen Kaserne), Germany
The antenna is a 22.0 ft × 4.6 ft (6.7 m × 1.4 m) elliptical reflector of open lattice construction, mounted on a small two-wheeled trailer. Rotation rate is 20 rpm, the BCC – Battery Control Central and the CWAR are synchronized by the PAR revolutions and the PAR system trigger. AN/MPQ-50 (Improved Hawk to Phase III)
