I.e., Where is the "ground" -- at its surface? Five feet below its surface??? I would venture to say that as its conductivity improves, the closer to the surface it is. 73, de Earl, K6SE _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
