It was always 48 for the real telecom players.

It was 48v
Then it was mostly 24v
Now it's going 48v
Just give it a little bit, it'll go back to 24v.
I'd rather get a power supply doing 26v to fix my problem in 2 minutes than
start changing things to 48v which would blow so much stuff up (epmp non gps,
ubnt M gear, half the Mikrotiks)

No, there's not really a good reason, it just means you have an extra part to
deal with.
We still use UBNT for our 2.4ghz stuff, but those are the only radios that
won't run off 48v on most of our new sites, so I've done some that are 48v only
and just use those things on the radios that need them. But if you have more
than 1 or 2 things that need 24v, it's generally more practical to just use a
bigger voltage converter and run multiple radios off it.

Yep, that was what I was thinking.
So, looks to me like there is no reason not to do 48 volts.

You mean like this?

Or do you have something better in mind?

Me too...
So, what appetite is there for an inline POE regulator that would convert
48 to 24?

ugh... I keep forgetting to use reply-to-all...
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 a converter you can stick on in line
with the radios, but that's kind of a pain if you have more than one or two,
and it's an extra part to fail.

I promise life will be easier if you just use 48V. :)

I'm trying to use a Powerbox Pro to power up two epmp APs. The 5
GHz is just fine but the 2 GHz is saying current too low. Both ports are
getting 23 volts and the cables are <10 feet (from the Powerbox Pro).
Does anyone know if the 2ghz requires more voltage possibly?
Spec sheet does say 23 volts min but it's weird one powers (5
ghz) and the other doesn't.
