Not at all. I was relating an experience which I hoped was accurate and
useful.

Kraus describes the "comparison method" on page 857 of his 3rd edition
of "Antennas". I used the reverse of his example, switching transmitting
antennas instead of receiving antennas.

Kraus` volume goes into many details of antenna testing.
