Brian,
Is it as simple as your signals that are failing in the chamber are
hidden under ambient on the OATS? Same frequencies? What frequencies (eg
signals in the 30 to 200 MHz range)?
All the absorber is suppose to do is make the metal walls and the
ceiling transparent from 30 MHz to 1 GHz (or higher) depending on the
quality of the material used to line the 10 meter chamber. Nothing really
special.

Subject: OATS vs anechoic
Good People,
Have tested at several sites. All are 'big' names and have a good
reputation.
The 10m fully anechoic chamber data indicates from +5dB to +11dB in several
frequencies; while the 10m OATS says the unit passes Class B, min -4.2dB.
Huh?!? What is the physics behind the difference between an outside site and
absorbers? Where are the Borg when you need them?
Brian
