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
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.
