During the early 70's I was consulting at Hughes to develop an AML transmitter/receiver system. It used 5 watts of amplitude modulation on 12.7GHz powered by a Varian Klystron. One of the applications was to connected TV between Hawaiian islands. It did that very well. The system could be...
The output of the antenna can NEVER exceed the power applied to it in a true 3D omni directional pattern. If you have a antenna that is rated for a million watts and you feed it with 200 mw, the power out of the antenna will be 200 mw, less losses in feed line and antenna efficiency. So as...
UFER (cement encased) grounds can explode when hit with lightning. It is a bad engineering practice to use the rebar or a wire encased in the cement for a “lightning ground“. The moisture in the cement vaporizes instantly when superheated during a direct lightning strike causing the cement to...
