Under 100 bucks for three ground kits and under 300 bucks for the ground kits, a ground bar, polyphaser, and copper strap. The copper strap is the most expensive part. Still cheap protection for the time and money invested in your repeater system.

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.
