In a perfect world it would all be 100% 48v (or hell even 100% 24v) but

Epmp comes with a 24v poe and if you've got say 100 feetish? you're at 23
volts..that's minimum boot for warm weather. If it loses power in cold (20F?)
it won't come back

I do feel your pain on this subject though because we have most
everything running on 48v and at sites that require it
depending on space requirement that I have there I just remove old 24v
system and add dcdc converter to take care of whats left on 24v.
Otherwise I just leave old supply.
We do
Me too...
So, what appetite is there for an inline POE regulator that would convert 48 to
24?

All UBNT devices that we use are 48V (AF) and all MT devices that we use
are also 48V now. You could always throw a small PoE switch (Netonix or
whatever) that can do both 24V and 48V. I realize this may not be the most
convenient thing for you to do..
I'm just saying - a lot of our problems
There's that too =P

Not every single UBNT radio... all the airfibers will happily take 48v.
Mikrotik is finally starting to make most of the new stuff handle 48v
(including the PowerBox Pro), but yeah. UBNT is the reason I still have to
use 24v on most of our towers...
They make dental floss for that :)
