I recently tried this on my multi band offset center dipole and would be interested in any comments.
300 ohm twin feed from antenna to near ground level; box there containing 4:1 balun which connects via RG8 to rig in second floor room. In the box ( one foot above ground) I connected outer shield of coaxial to horizontal copper earth pipes below ground. I was getting RF in shack and poor SWR on 80M band. The result now is that I get good SWR across 80M band and no RF in shack. I am getting good signal reports, but have not had the opportunity to check on the amount of power that is actually getting out of the antenna.
