Doesn't a good earth ground help remove stray RF from the shack? along with

Ferrites can help, but if you really want a "good" RF ground, it should
be less than about 1/10 wavelength long at the shortest wavelength you
want to use. So about 3 feet in the 10 meter band!
If it's not that short, it can be "tuned" to be an integral number of
half wavelengths at any one particular operating frequency... but then
your "ground" lead becomes part of your antenna system. It will radiate
and receive.
So it is good advice (as someone said) to be sure your antenna is well
balanced and as far away from the shack as possible. In that case, the
RF ground is usually not needed. But a good AC & lightning single point
ground system is still important.
