[1] [2] [3] He was the American author of numerous amateur radio and radio engineering texts. He is best known as the author of The W6SAI Antenna Handbook [ 4 ] and fondly remembered for the 1959 Radio Handbook .
The ARRL's "Antenna Book" makes extensive use of EZnec and includes many example files (in .EZ format) to model amateur radio antennas. Opens .EZ files. (EZnec also works on Linux using Wine, or on Raspberry Pi using Wine inside ExaGear). 4nec2 - A free NEC2/NEC4 implementation for Microsoft Windows.
A two-element quad antenna used by an amateur radio station A 4-element amateur radio quad antenna. The two men working on it show the scale. The wire loops are almost invisible, suspended on the ends of the crossed supports. A quad antenna is a type of directional wire radio antenna used on the HF and VHF bands.
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 Moxon [2] (call sign G6XN). [1]

In radio this device is also known as a dummy antenna or a radio frequency termination. It is a device, usually a resistor , used in place of an antenna to aid in testing a radio transmitter . It is substituted for the antenna while one adjusts the transmitter, so that no radio waves are radiated so that the transmitter does not interfere with ...
