My 19th edition of the ARRL Antenna Book treats additional power loss
due to SWR on page 24-10.

Richard, I have an 18th edition, and the formula it gives does not
factor in the angle of the reflection, and so is an approximation.

I don't know if that applies to the 19th edition.

Back to my original post, I was not in search of a formula for an
exact solution, nor a reason to want an exact solution, but rather
whether anyone has seen the derivation of Michaels formula quoted in
QST Nov 97.

Thanks for your help.

Owen
