That would be an interesting experiment.If I get around to it would you 
like to know the details.

John,

I used an aluminum foil counterpoise with a OBIT
powered coil. This seemed to work fine for
prototyping and testing. However, I can't verify
maximum spark length when compared to a proper RF
ground. By the time I constructed a proper RF ground
I was running a 12/60 and had 4 foot arcs.
