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] It takes its name from the amateur radio operator and antenna handbook author Les ...
The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [ 1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [ 2] [ 3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).
In radio engineering, an antenna ( American English) or aerial ( British English) is an electronic device that converts an alternating electric current into radio waves, or radio waves into an electric current. [ 1][ 2] It is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with ...

Shortwave broadband antenna. A shortwave broadband antenna is a radio antenna that can be used for transmission (and reception) of any shortwave radio band from among the greater part of the shortwave radio spectrum, without requiring any band-by-band adjustment of the antenna. Generally speaking, there is no difficulty in building an adequate ...

A beam waveguide antenna is a type of complicated Cassegrain antenna with a long radio wave path to allow the feed electronics to be located at ground level. It is used in very large steerable radio telescopes and satellite ground antennas, where the feed electronics are too complicated and bulky, or requires too much maintenance and alterations, to locate on the dish; for example those using ...
The antenna feed system or antenna feed is the cable or conductor, and other associated equipment, which connects the transmitter or receiver with the antenna and makes the two devices compatible. [ 1][ 2] In a radio transmitter, the transmitter generates an alternating current of radio frequency, and the feed system feeds the current to the ...
