Ray, I suggest that you obtain the most recent edition (2011) of NFPA 780, the Standard for the Installation of Lightning Protection Systems, and install a proper lightning protection system for your antenna and mast per that document. It can be purchased for about $40, but you might find a copy in a municipal library.
Please be aware that installing an antenna atop a building that has no lightning protection system installed may impose liability on you, if the antenna is not protected by a proper system and a fire or other damage occurs due to a lightning strike. In some landmark cases, the insurance company declined to pay for damages resulting from a poorly-designed and/or -installed LP system. Choose wisely... 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ray Brown Sent: Tuesday, August 17, 2010 8:55 PM To: [email protected] Subject: Re: [Repeater-Builder] Polyphaser Question What do you do when you want to install a small UHF linking repeater on a 4-story building that has no lightning protection on its roof?
