i think the more important thing now is to point out to the arrl the error
of using that form of the reflection coefficient in place of the
'conventional' one in the latest antenna book so it doesn't become gospel
in
the future.


I have contacted n6bv and he reports they have already changed the 20th
edition of the Antenna Book back to the 'conventional' rho and changed the
power analysis to use the full hyperbolic formlations for voltage or current
to calculate the line loss.
