Correct... that should be the minimum area used.


LOL!!!

Ah yes, the elusive and little known 3 squared ratio for mobile 1/4 wave
antennas.

No... just that anything smaller will not constitute a massive enough
plane to be of any use.

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.

What's new? Glad you asked...

Blah, blah, blah. You are starting to sound like Skippy with his "it's
part of a bigger picture" excuse. Stuff the BS and show the math, you
hack!

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.

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'.
