Don:
Not meaning to single you out, but your post tweaked a concern of mine.
Are we all operating in a sense of fear in this forum? Do we really
have to obfuscate the facts by referring to an "original antenna" and "another
antenna"?
Or am I the only one who would like to know exactly which antenna and
test lab that you're talking about?
