HI John, Thanks for the information. FYI. The article in Conformity states that outdoor testing is permissible however testing is "...limited to specific ISM frequencies (frequencies where RF transmission at the required level are legal)." What I don't know is if this practice is only permissible for in-situ testing or if it can also be used for large objects at a test facility.
I am getting the impression that if you do use this method that a competent body should be involved especially since the entire band is not being covered. Someone of some higher authority will have to sign off on that I'm sure. At least I would want them to.

You may well need to go to a test house which has a big chamber. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
