Ohm coax with a 1:1 isolation transformer at the antenna. I intend to run a

You seem to be implying more than one measurement, and that with those
measurements you can separately determine (radiation resistance + loss
resistance in the vertical and coil) and loss resistance in the ground
system.

Can you elaborate?

Perhaps a block diagram of your measurement setup might reveal what
you are thinking. (If you need a tool for drawing schematics in ascii
text, Google for AACircuit. Alternatively, sketch it, scan it and
publish it on a web site somewhere... DON'T attach it to your news
post.)
