[Elecraft] Ground Strap

[Stuart Rohre]

Don't forget 8 feet is a quarter wave on 10m.  Thus, George's comment
certainly applies at 10m band.  For that band you can augment the water pipe
static discharge ground with a series tuned circuit and 8 foot insulated
conductor along the base board of the shack to keep the radios chassis at
near zero RF potential.  Also, consider the furtherest radio in the chain
will have a differing RF ground situation at 10m (and other bands) than the
one closest to the 8 foot direct run to pipe.

Many modern houses do not have metal pipe outside the foundation, and all
the way to the main.  In areas here with that problem and with poor ground
conductivity, we are burying circle grounds of bare copper wire around the
building, to have a common voltage reference in case of lightning surge.

With 100 to 200 feet of no.10 or larger wire, you can get an adequate ground
buried 18 inches under the surface.  When we have solid limestone below
that, that is about all we can do.
