It's no different than with any conductor. If your stereo speakers are playing several notes at the same time, this means that the voltage across the terminals and the charges inside the wires are *not* vibrating back and forth in a sine wave. Instead several sine-wave motions are being added together. If you connect several different signal generator outputs to your oscilloscope, you can see what such a composite signal would look like. On an antenna we can either imagine that there are several separate signals having different frequencies. Or we can imagine that there is just one current/voltage signal, but it's a sum of many sinewaves of different frequencies. ((((((((((((((((((( ( ( (o) ) ) ))))))))))))))))))) William J.
