| Can you run a feedline to the service entrance to be bonded to the service ground, and then run it inside the house to the station location? -It sounds like you're talking about running a single wire from the service ground to my shack equipment from inside the house. My situation I'd be looking at about 125 feet of wire. I thought this line needed to be kept as short as possible for RF reasons? I heard that if you had a long distance to connect your shack ground to the service ground, you needed to do it outside and drive ground rods every 8 feet or so until you reached your service ground rod. |

| I just got my General in November, and I am in the design stages of a beginner's level part-time ham shack. This will be set up and used on weekends, days off, etc. I am gradually acquiring equipment (antenna, mast, radio, etc) as the funds become available. Unfortunately with kids in the house, my only available location is an upstairs office bedroom that is on the opposite side of the house from my service panel. I know all about grounding requirements, and how everything has to be connected to the service ground, etc but I could be looking at about 20 ground rods to get everything to reach and bond to the service ground. Plus I need to find a solution for that long wire dropped from the second story window for the initial ground rod. I recently read about a technique using RG-8 coax which involved combining the shield and center conductor to connect to the ground rod, while connecting only the center conductor to the radio/ equipment in the shack. The shield and center conductor on this end would be joined with a capacitor. I believe it was designed by N8SA (William Chesney). It is claimed that this method will resolve both RF and electrical ground issues, while "fooling" the grounding system into thinking the wire length is much shorter than it actually is. 1) Has anyone tried this technique or know anything about it's validity? This seems to be the only solution to get the ball rolling on my grounding system. 2)If my shack is only going to be set up and running on a part time basis (weekends, etc) how elaborate does my grounding system need to be? |
