Sam,
You should also consider the radiation may be from multiple sources on
the
EUT. Polarization of the source may not be the same at the substitution
antenna. Try 0, 45, and 90 degree polarization of the bi
Can you please explain why? The receiving antenna just responds to the
field strength at its position; it doesn't 'know' anything about the
source - it cold be an EUT at 10 m or a distant TV transmitter or even a
cosmic source.
This isn't the issue. The receiving antenna, as you say, can't
by an antenna of specified
construction and gain.

Sam,
I think you did it right with one AF and one gain. There's a problem with
that method. You need more information needed to make the _results_
right.
Given a certain power at the antenna terminal, and a known gain and
efficiency, you can calculate

Hi Group,
I have been asked to perform field strength measurements using standard
radiated methods as well as substitution methods on the same sample(an
intentional radiator). While I have plenty of experience making
radiated measurements, I have never made a substitution measurement. I
