Heat and Humidity

Did you know that the heat and humidity can have an impact on radio and television signals? The hot and humid weather and the density of the air help the signals travel very long distances. We have noticed when we watch television programs off our antenna, that often other channels try to cut in and this is the reason. This is called tropospheric ducting and has made the local channel difficult lately. When the weather is right, two other channels, much father away, travel here and interrupt the signals. Interesting, huh?
