Jim succested the Counterpoise groud solution, if a "convential" HF
earth is not in reach.

My questions:

Is this wire carpet to be layd on the floor direct under the coil? (coil system standing on this wire carpet?)

Yes...


Is Wire carpet conected to secondary bottom, NST case and to wall
plug ground?


Yes.. Definitely to secondary bottom (with short direct wire).. also should be connected to electrical safety ground (so that if something shorts to the ground screen, like a HV wire, you don't have a safety hazard).

One could put a RF low pass filter on the safety ground connection.. (i.e. a big choke).. The safety connection is for DC/line frequency signals.


Is this solution also OK, if applyed, say in third floor of a
building -?

Yes, it works just fine..

If floor is not concreet, but wood? (a Swiss alp cottage...)

Sure..



I keep you buisy .. Fritz
