John (+ others):

I measured the Rac of my 200ft perimeter loop in Ellsworth at 500K on 
Friday. This loop is made from uninsulated 3/8" Cu tubing resting on many 
limbs having full foliage. The value was about 0.8 ohms compared to 0.4 at 
185K The increase in efficiency between 185K and 500K as the result of the 
increase in radiation resistance and a doubling of the loss resistance 
(assuming no other effects) should be approx 1/2( 2.7^4) = 26.5X. Can't wait 
to try this out as a 600M radiator!
