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.
