So, ya reckon frequency has *any* bearing on this guess? What formula are
you using to come to this conclusion?

Sure it does... but remember that antenna thoery is quite complex. Not
sure there is any one formula for figuring this. The plane's size and
shape will have a large impact on radiation pattern... amoungst other
parameters.


So, you have decided that 9 square feet is about right based on what theory?
I've built yagi's, ground planes, collinear, dipoles, etc. I was just asking
you to back up your theory. This is not some cutting edge science that
cannot be verified with today's math. Please don't allow yourself to be
proven a blowhard again. You made the statement, back it up.

I only said that a 3'x3' area of ground plane would be the minimum size
that I would recommend for such an installation. Never hinted there was
an exact formula to substantiate that recommendation.

What's new? Glad you asked...

Actually, there -is- an exact formula for the surface area of a ground
plane. And at 11m it's nowhere close to 3' x 3'.

Well don't just stand there Frank... what's the formula?

Don't you know? Aren't you an engineer?

Frank, why don't you just say you made up the part about the formula...
LOL
