Is it a Wisconsin thing that you have a to have any wire that penetrates the building "envelope" grounded within 20 feet of penetration to meet code? Seems like if you have to ground it anyway within 20 feet of entry, put the POE there and then they can have their extender wherever they want along the rest of the run.

Sometimes we get a win.

If it does manage to keep the radio powered i see it burning out the poe circuit. hes fighting me on putting the cambium PSU at the midspan point and using his own POE to power the extender. Ive been overruled about telling the customer no, so its happening, but I want to make sure my math is correct using https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html 24guage, 30v, .5 amp, 400 feet shows 10v drop. but im not sure about the resistivity field this is a guy who runs constant latency monitoring and initiates tickets on every blip, so i see this radio move just becoming a nightmare with this midspan extender in play -- AF mailing list AF@af.afmug.com<mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: ja...@litewire.net<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: af-boun...@af.afmug.com<mailto:af-boun...@af.afmug.com> You received this message because the domain afmug.com<http://afmug.com> is on your allow list. -- AF mailing list AF@af.afmug.com<mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: ja...@litewire.net<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: af-boun...@af.afmug.com<mailto:af-boun...@af.afmug.com> You received this message because the domain afmug.com is on your allow list.
