My remote station is approaching completion. A 70' tower, wireless internet,
solar power and RemoteRig with a TS480 is all operational. Still in progress
are the antennas to be mounted, and lightning protection. I have a question
about grounding. The electronics are housed in a valve box--a galvanized steel
cylinder 5 feet in diameter and 4 feet tall, with 3 1/2 feet of that in the
ground. A removable steel lid covers it. All cables are in PVC pipe and enter
the housing under ground level, and the valve box is 12 feet from the base of
the tower.
The grounding system will consist of 9 ground rods, 3 connected to each leg of
the tower and extending out from the tower. The valve box will also be
connected to the grounding system. Polyphasers will protect against surges.
My question is, can I install the surge protectors inside the steel housing, or
should they be mounted outside the valve box? I'm thinking that the steel
cylinder possibly acts as a Faraday cage, and the grounding connection and
surge protection should be attached on the outside wall of the housing. Any
comments or suggestions, please?
Thanks!
