This therom simply states that: " An antenna's performance is inversely proportionate to the temperature in which it was erected." So, if you put up an antenna in 90-degree weather, it will have an efficiency rating of 10 percent. Perhaps that is why all those antennas that are put up in bitterly cold January weekends work so well. Note that this theorem is based on the Farenheit scale. It would be an interesting study to see how things worked in a Celcius scale. 73, Sean Kutzko, KF9PL Elkhart, IN (The armpit of Cyberspace) kf9pl@cris.com ```
