The building has a steel support structure, I'm sure. You will need to bond to that as a start.

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: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Ray Brown Sent: Tuesday, August 17, 2010 8:55 PM To: Repeater-Builder@yahoogroups.com 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?
