Hi Dave,

Many thanks for the comeback with you loop parameters. Have a few questions
about these:

Loop conductor is two runs in parallel of 7/1.5mm aluminium-- your bog
standard 11 kV overhead drop-lead stuff.
I assume this is two strips of 7mm x 1.5mm Al? The two are running in
parallel, but assume they are they also connected in parallel at their ends
rather than in series?

and effective resistance at 180kHz of 0.99 ohms - a bit on the high side,
I suppose the skin effect losses are pretty high with a 1.5mm thickness
since this is about 10 times the skin depth. This is what makes larger diam
solid or stranded conductors not worth much (unless Litzed.) What are the
dimensions of your loop and how high is the lower portion above ground?
