Mitch:

Thanks for the pictorial of the loop.. I have been trying to 
mentally picture what you were doing, and the diagram cleared
it up for me.. 

I do have a couple of questions if you can take the time to
address them..

#1 How high above ground is the bottom side of your loop ??

#2 Do you have a Radial Field - of any sort - underneath, or
leading out from under the loop ?? And if so; will you describe
how you have the Radial Field laid out on the ground ??

Thanks OM for your time and reply to the list, as I'm sure there
are others who will be interested in your description..

73, and Merry Christmas to you and your family from:
