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.
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.
A 20-meter-long T²FD antenna, covering the 5-30 MHz band. The T ilted T erminated F olded D ipole ( T²FD , T2FD , or TTFD ) or B alanced T ermination, F olded D ipole ( BTFD ) - also known as W3HH antenna - is a general-purpose shortwave antenna developed in the late 1940s by the United States Navy .
Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]
AN/MPN-25 ITT product that scans the PAR coverage area and capable of scanning 360 degree using the same antenna. The system then process the raw target data to form a data word sending it to a computer display operating on Solaris. It is a 30 nmi (56 km) asr coverage and 20 nmi (37 km) PAR coverage.
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 ...
