I’m considering mounting my PVC enclosed 8 segment CoCo antenna on the roof and have been thinking about the need for lightning protection. My instinct is to stick a grounding rod in the ground and connect it to the coax outer conductor with a grounding block as you would a regular TV antenna.
The more I think about it, i’m wondering if it’ll do any good. The house is surrounded by huge oak trees, the antenna barely peeks over the roof line, and of course grounding the coax outer conductor doesn’t actually ground the (plastic) mast.
Then again, with a large enough electrical potential, anything is a conductor, so better provide a safe path to the ground.
