[TowerTalk] Practical grounding etc vol 145 issue 54

[Russ Dearmore via TowerTalk]

Try measuring the resistance of hardened concrete and I bet you'll never trust it again as a ground.  It's the rebar in the concrete that the #4 solid copper is attached to that makes it an ufer ground.  We (electricians) use this ground in the desert mostly because the ground rods don't do so well in desert soil, and plumbing can have pvc pipe so that method isn't foolproof either.  When I lived in a remote area of the Mojave desert I attached my ground, to my water well pipe casing that went down about 160' to an underground river, and the other end to the tower.....  Best ground I ever had...   Russ  K5ZZR
