DX Savant,

Yes - I have one of these "Ground Anchors" as described
down the hill at about 75 Feet from the side of the house.
Currently the Inverted "L" Wire Antenna Element is a 30
Feet Vertical-Up-Leg and 70 Foot Horizontal-Out-Arm;
going from North-East to South-West.

IMHO - For Noise Reduction here - It works about as well as
the Two Snap-On Ferrite Cores at each end of the Coax Cable.

I did it more for 'additional' Lighning Protection :
+ 75 Feet Away from the House
+ Ground Rod
+ Shape 90* Bend
+ One Foot Under-Ground Metal Tube


hope that helps - iane ~ RHF
