Hi Ted,

I've been following your postings with interest but with no time to respond 
until now. Your Rac of 1.75 ohms is a bit high for a 200ft perimeter loop of 
#8 but your 60/40 aspect ratio is not ideal and will have higher ground 
losses than the 50/50 loop. What is the height above ground for the lower 
horizontal leg? This is another variable effecting the Rac.
