Grounding systems -- need the help of some good elmers

If lightining, here's a good place to start. http://www.polyphaser.com/NR/rdonlyr...182/TD1016.pdf Danny, K6MHE |

I'm looking to create an RF ground. A couple of ground rods is not going to make much of an RF ground. Do you actually need an RF ground? Being you will be on the 2nd floor, I bet you would be better off without one. What will the antenna be? You would be better off to use a "complete" antenna, and that way you will not need an RF ground in the shack at all. An RF ground should always be under an antenna the way I see things. Trying to rig up an RF ground on the ground floor, and then rigging a wire from it, up to the 2nd floor, is a mistake, and will just act like part of the antenna. Myself, I would not even bother. Heck, I'm on the ground floor in this shack, and I don't use an RF ground to the shack. Haven't in nearly 15 years... MK |
