[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 Amateur radio R-S-T system signal report format currently in use was first developed in 1934. [citation needed] As early as 1943, the U.S and UK military published the first guidance that included the modern "Weak but readable", "Strong but distorted", and "Loud and clear" phrases. [citation needed]
One "S" difference should correspond to 6 dB at signal strength (2x voltage = 4x power). On VHF and UHF receivers used for weak signal communications, S9 often corresponds to 5 μV at the antenna terminal 50 ohms. Amateur radio (ham) operators may also use a signal strength of "20 to 60 over 9", or "+20 to +60 over 9."
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]
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1]
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.
