make comparisions between several antennas and find a dud that is 10 db
below the rest, but to resolve 2-3 db over a dipole with accuracy just
won't happen to my satisfaction. There are too many things that can
change and and go wrong in the worst way.
Obviously you haven't read our antenna comparison reports. Our protocol is a
pretty reasonable solution to standardize on-the-air antenna measurements by
comparing the antennas under test to a dipole and was arrived at after
discussions with very knowledgeable antenna gurus (e.g. W4RNL, W8JI, etc.).
We undertook all of the work for our tests because there was no
standardization and published manufacturer performance figures couldn't be
trusted.
While not perfect, they are the only antenna comparison tests (yagis
and verticals) that offer credible data and analysis.
