Re: [AFMUG] Surge Suppressors
Talking CAT5 and not RF so not a huge issue. The bigger problem is near end cross talk (NEXT) problems when the surge suppressor is very close to a device like a switch or radio. There is SNR on GIGE but normally return loss, FEXT, NEXT and things like that are more of a problem. -Original Message- From: Keefe John Sent: Friday, June 10, 2016 2:07 PM To: af@afmug.com Subject: Re: [AFMUG] Surge Suppressors What about insertion loss causing cables to have SNR issues?

Re: [AFMUG] Surge Suppressors
We had problems with the port flapping on one of our B5c's when it was running off of a Packetflux injector (with no surge suppressor)... after replacing everything other than the radio itself, I ended up hooking it up to a GigE-POE-SS instead and it's been working fine ever since.

Re: [AFMUG] Surge Suppressors
I'll be using the stock injectors more than likely, so the GIGE-APC-HV would be a good match?

Re: [AFMUG] Surge Suppressors
Yes, that would be correct - that's what I used on ours. If one was wanting to use the stock (or some other) PoE, I assume you would just use one of the GigE HV surge suppressors.
