If your ground wire is an appreciable percentage of
a wavelength, it is a radiating element grounded at
one end, i.e. not a ground. An artificial ground
might help to reduce RF in the shack.

If your antenna is balanced, you don't need an RF
ground.


Cecil:

Say I had a situation where I must use a ground wire which IS an
appreciable percentage of a wavelength ... and don't wish it to radiate.

Could I accomplish this by using coax as the ground-wire and choking the
outer braid by sufficient windings on a toroid core, and grounding the
center conductor and the braid to earth though good and deep grounding
spikes or wires?
