Hi Brian at these frequencies you can roll an insulated wire along the
ground and get a pretty big signal. The reason is that they "ground" is not
necesary at ground level due to the skin effect  in poor soils it can be may
metres below that (It probably wont work on the sea-shore).  There is then
not so much of a problem unless you get a direct strike nearby and big earth
currents. In that case there is not much that will save you. It is certainly
worth a try.
