Ooohhh, did I hit a nerve? I guess it's a good thing that Mike's loop has
all that extra high angle radiation, or I'd never hear him!

Did you ever stop to think that Mitch might not have been wearing pants at 2
A.M.? And that 20 dB figure sounds kind of vague. You did keep a log of the
signal strengths, right?

Mitch: use a recently calibrated thermocouple meter, not some cheap thing
with diodes and donuts. And get the calibration certificate notarized. <g>
