Polyphasers inside the shelter mounted to the the common-point ground bus bar for all of the indoor equipment, with the indoor common-point ground tied into the site ground system using low L/C conductors (3" Cu strap preferred, #2 AWG for short runs, avoiding right-angle bends). --- Jeff > -----Original Message----- > From: Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com > [mailto:Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com] On Behalf Of Mike > Besemer (WM4B) > Sent: Thursday, June 21, 2007 10:13 AM > To: Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com > Subject: RE: [Repeater-Builder] RE: VSWR Issues - Repairs Complete > > No. but that was recommended and we're considering.
