What radios, specifically Gino? From: Af [mailto:af-boun...@afmug.com] On Behalf Of Craig House Sent: Sunday, October 25, 2015 12:51 PM To: af@afmug.com Subject: Re: [AFMUG] Site Grounding - what we are doing wrong?
Gino We used to loose a lot of equipment as well. Daniel White gave me some advice 10 years ago and we started immediately noticing a difference. The suggestions was good shielded cable with a ground strap every 75' minimum. Since then we have changed a lot but still lose very little. The main thing we have changed is to keep our ethernet cables as absolutely short as possible. I mount a box on the tower and run AC power up to it. Install a Surge strip for the Netonix switch at the top of the tower and try to keep all cable runs to less than 30'. I use fiber up the tower every chance I get and since the Netonix switches have SFP built in it is really not much extra cost for the fiber. I have come to the conclusion that we will always lose some things but it has helped so much. We dont usually do anything special to "ground" our stuff unless the tower has a propensity to attract lightning. Not sure if this helps you but it has worked for us Craig ________________________________ From: "Gino Villarini" <ginovi...@gmail.com<mailto:ginovi...@gmail.com>> To: af@afmug.com<mailto:af@afmug.com> Sent: Sunday, October 25, 2015 11:31:05 AM Subject: Re: [AFMUG] Site Grounding - what we are doing wrong? Tushar, when you say ground block you mean a surge suppressor? On Sunday, October 25, 2015, Tushar Patel <tpa...@ecpi.com<mailto:tpa...@ecpi.com>> wrote: We used to loose lot of radios too. We do following now and it seems to help (loosing less). At top on the tower: We put all AP on stand off (MTOW-p), then we have grounding block mounted on the stand off at same level as AP, then less then 2 feet of cable going from grounding block to AP. All shielded cable and grounded to tower. We have lost few ground block on tower but it seems to save radios. Some ideas came from orthogone system product and their grounding guide lines. At the bottom Shielded cable going to grounding block and then to equipments.
