Barry,
thanks a lot for the information. I'll check the article as soon as possible.
Back to my latest post on the subject, I realized I missed an important detail
in the last point (4). Quoting myself:
"for NSA measurements and site validation you can
limit the job to horizontal polarization
Hi Paolo,
I am interested in this topic, but don't have much available time to
participate the discussion.
You mentioned the far-field in item 3 of your message below. You might be
interested in an article "The Fer-Field: How Far is Far Enough?"

Robert,
there are a couple of points that came up in your posts that I would like to
more fully understand.
1. "...the site under test is verified against the performance of the site on
which the antenna factors are calibrated".
I honestly don't get this point. The applicable standards (ANSI C6

This is a discussion which starts up at least once every year. There are
some issues with measuring NSA which are not very well understood including
antenna factors.
First of all, how you test and which factors to use should not be a matter
of opinion. Unfortunately, the standards do not complet
Hi Pierre,
did anyone reply to your post ? I would be a bit surprised in that case, given
the high and broad level of EMC experience among us.
I am pretty much interested in how your NSA and antenna calibration measurements
are going and what results are you getting. This subject is widely cover
