Sorry I was thinking only about engineering, not practical maters. Yes, you are right, there is more to it. The rules are all local, the US does not have a national statute. So you need to check with local building department. But yes all antenna masts must have a ground wire. You'd put a wire and a clamp on the pipe and lead it off to a ground. Some will go further and place a lightening arrester in-line with a antenna cable. But in most places the local code only requires the mast be grounded. Nothing will protect from a direct hit, for that you'll need a metal tower separate from the house and an elaborate grounding system on the tower. But a simple grounded pipe mast is no worst then the vent stack on a gas furnace. The other safety concern that must to told to anyone putting up an antenna is to look for overhead power lines and be 100% certain that even a huge storm could never case the mast to fall onto a power line or come even close to one, even if the utility pole falls and your mast falls And while we are at it. There is a danger of falling from the roof. Always use a safety harness if you are 6 feet above ground or more. and never work on top of tall building or towers alone, have a spotter Did I leave anything out? -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
