These work great in this type of application if you can talk them into running fiber:
https://mikrotik.com/product/RBFTC11 <https://mikrotik.com/product/RBFTC11> If you have AC power at the remote site you can power your radio from the POE port. If you have to run fiber + power there are a lot of inexpensive DC/DC converters like these that will let you stuff 48V down the wire and get clean 24V at the far end: https://www.cui.com/catalog/dc-dc-converters/isolated?[0].sn=Package%20Type&[0].sv=DIN%20Rail Mark > On Sep 1, 2021, at 9:18 PM, James Howard <ja...@litewire.net> wrote: > > 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. > > From: AF <af-boun...@af.afmug.com> On Behalf Of Steve Jones > Sent: Wednesday, September 1, 2021 4:45 PM > To: AnimalFarm Microwave Users Group <af@af.afmug.com> > Subject: Re: [AFMUG] resistivity of cat5 > > all but the exterior cable run of maybe 12 feet. theyre extending their > building out and putting up another building in the current LOS > > On Wed, Sep 1, 2021 at 3:43 PM James Howard <ja...@litewire.net > <mailto:ja...@litewire.net>> wrote: > Just out of curiosity, if he can put a network rack at the midpoint, how much > of this is inside buildings? > > From: AF <af-boun...@af.afmug.com <mailto:af-boun...@af.afmug.com>> On Behalf > Of Steve Jones > Sent: Wednesday, September 1, 2021 12:26 PM > To: AnimalFarm Microwave Users Group <af@af.afmug.com > <mailto:af@af.afmug.com>> > Subject: Re: [AFMUG] resistivity of cat5 > > thats what i suggested trying first, customer wanted the extender, irritating > > he finally has caved now and will be putting a network rack in the midpoint > and is going to place a managed switch there instead of all this other > unsupportable cobbling.
