waves of average power actually exist.

Roy, I have been involved with the evaluation and repair of FM and TV
broadcast antenna systems where the initial problem was a failure in the
antenna, which then produced a high mismatch between it and the main
transmission line.

The allegedly non-existent nodes along the transmission line for this
condition did a fine job of melting holes in the inner conductor and Teflon
insulators of 3-1/8" OD (and larger) rigid transmission line, at
1/2-wavelength intervals over a considerable length of that line.

What other phenomenon do you believe caused such a result?

RF
