Re: RF ground - what if you can't use a ground rod?

Hi again Thomas,

In this case you can use a counterpoise, which is a chunk of hardware cloth spread out under your coil, and connected to RF ground on your coil. If you give us an idea of the power level of your coil, we could tell you how much you will need. Otherwise, you could use power ground for a single NST.

Our ground here is solid granite, topped by a couple feet of rock-hard
clay, topped by a handful of inches of soil. No way am I going to be
able to punch in an 8' ground rod for the RF ground (wish I'd thought of
this before I bought it). Are there any other alternatives? Can I bury a
couple square feet worth of copper plate under the soil, maybe? Or maybe
take the rod and bury it horizontally? Any suggestions?

Thanks again,

Tom
