I do note that my ARRL Antenna Handbook (18th edition) and ARRL Handbook
(2000) both use rho, however they reckon that rho=(Za-Zo*)/(Za+Zo) (where
Zo* means the conjugate of Zo). They do this without derivation, and seem
to be in conflict with the derivation in most texts. I suppose the
derivation is buried in some article in QST and in the members only
section of the ARRL website.



Thank you, Owen. Les Besser agrees with the
ARRL.

However, in almost all practical calculations,
Zo is purely real, so that gamma=(Za-Zo)/(Za+Zo) is
used in most texts, and the results are the same.




Owen,

There was a big discussion about this last year, and somebody posted that
the ARRL was going to eliminate the conjugate reference.

Going to? It says 2000 on that ARRL Handbook!

They are NOT going to eliminate the conjugate
reference, because it's correct.
