Plugs and Wires

Dell, You are correct, 1/4 wave and ground plane... loops and nodes.
What I always think is neat about RF, is that is composed of transverse electric field and magnetic field waves 90 degrees apart. The math came long before the discovery of RF.

I saw a video about Tesla on netflix, he invented tuned RF spark gap radio receivers and transmitters long before Marconi. Marconi copied his work and submitted patents without even a good understanding.

Tesla reported he received a signal 1-2-3... Over and over, and suggested it could have been alien, Think of how that would have been, to have a receiver in a near at the time of pre electricity and earthly transmitters. Now days with all the RF, signals and noise, we no longer have the ability to hear ET. At least close to earth.
