Hi Glenn Seems a lot of work for a relatively simple rf ground. Why not just take a piece of copper tubing and lay it in a shallow trench and bond your ground wire to it? RF doesn't penetrate the ground very far, so a deep trench wouldn't be needed.
Glad to see you're still around. Haven't heard you on in a while. 73, Bob N6WG -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Glenn Maclean Sent: Wednesday, July 13, 2005 7:48 PM To: [email protected] Subject: [Elecraft] Station grounding question I recently up graded my house electrical panel from 100 to 200 amp service. In order to do the up grade I had to install a Ufer ground which was 20 feet of bare #4 copper wire in cement. Our local code allowed a 10 foot run of wire in a U shape in a 9 inch wide trench. The wire had to be 3 inches above the dirt 3 inches from the side of the dirt 3 inches between the wires and three inches away from the dirt on the other side of the trench. That allows for 3 inches of cement all around the bare copper wire. The more I found out about Ufer grounds the better they seem to be to me. The PH factor in the cement and the fact that the cement never completely dries out and retains moisture make it an excellent ground. This leads me to my question. Is anyone out there using a Ufer ground as a counterpoise or to ground their tower and station? This seems way better than the old ground rod pounded in the dirt. Any comments would be appreciated.
