Chris:
The advantage of a full anechoic chamber is that you don’t have to worry about
reflected signals messing up your pattern measurements. OTOH, full anechoic
performance of a chamber is not easy to achieve, as you get reflections off the
darndest little things.
I think I might try

I did some pattern testing in a 30’ x 24’ x 9’ semi-anechoic 461-style
enclosure (right, with the big table-top ground plane still in the chamber). I
did patterns at various times for 2.45 GHz Wi-Fi, 300 MHz and 225 MHz, usually
at a separation distance of 5 meters. Both the EUT
First follow-up to the original post. Let me thank everyone for their
interesting responses so far. As always an education.
I can tell you it is NOT the 900 MHz wireless phones. We disconnected
both of them from AC Mains and telco. We also turned off the outside
motion sensing lights.
Nothing I say represents the opinions or policies of my employer.
I am not a scientist, so tend to be rather practical and use models that are
known to work. I am not a writer of the likes of Clarke, DeCamp, Asimov,
Bruner, et al; so I am not an adroit thinker of future possibilities or

Any Motorola Canopy broadnand there? They use 915 MHz guided wave

Not that it applies to anything you are trying, but one of our groups needed to
characterize some radiating devices.
We set up the OATS mast with the receiving antenna and positioned it vertically
over the device, which was aimed vertically up into the blue.

The latest fad here for banning or regulating something as a drug, is sugar.
The claim is that sugar is causing the obesity epidemic.
The one side uses all sorts of names for sweetener with calories (verses those
