In our soil (Rocky Mtns) the copper 1 inch pipe does not play. Up here
a good way to make a 5 ft pipe into a 6 inch pipe is try to drive it
into the ground. What I've been able to do is get copper clad steel gnd
rods in somewhere between 18 inches and 3 ft. My 2 wire bidirectional
700 ft Beverage has directivity of perhaps a couple S units, no more, I
guess that would be 10dB tops? Maybe I should be using radials however
the critters would make short work of them. I do have a ground wire on
the ground between the ground rods at each end. The RG6 shield shares
the feed end ground stake, perhaps using a second rod just for the
shield would help?
My local supplier of gnd rods, Home Depot, seems to be supplying
aluminized steel now vice Cu clad. I hope they work as well. I'm at the
far end of the supply chain.
