Thanks Don and Gary for a better description. Gary I really liked the descriptions and explanations of radiation resistance especially the one of the mobile antenna. That's the one thing that a lot of folks don't quite understand. It's what I call antenna efficiency. I've been told that the radiation resistance of an 80 meter base loaded mobile antenna is less than 1 ohm. IF YOU COULD, deliver a 100 watt signal to this there would be 100 amps of current and the Q would be so high that you wouldn't have enough bandwidth for the audio spectrum.
Here is a example of a real short antenna. I tried to push some power into the 1KW tank circuit of my final once with the final turned OFF, by connecting the driver output to the output of the 1KW rig. The big tank capacitor ARCed over before I got 15 watts into it. John Coleman
