It is handled the same is for other pipes that come up through the rook to vent plumping. And yes you ground the pipe just like you ground an old off-the-air TV antenna mast and so on. My VHF (two and four meter) antenna and by HF wire antenna all have lightening arasters and big ground rod systems, and the ground rods are tried together an. But you know what? If you simply place an automotive "puck" type GPS antenna on your roof you have to do the same thing. It must be grounded the same way, same lightening protection and so on. So in the end you may as well put up a professional looking and permanent steel mast. It is not that much more work. > > Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
