Or a person could buy a set of up down transformers to increase the
voltage going up the tower to avoid voltage drop.
Of course, running 110 up to the top is probably easier.

Isn't POE DC?

There is no reason one couldn't do a custom POE that was AC.
A couple thoughts...
To maintain a max input of 48VDC, (to be under the low voltage codes),
and to deliver 50W topside, is going to require a 14-16AWG wire pair
and a 48V 60W supply at the bottom.
I suspect that you will need to
Belden makes this, but I don't have a number for it.
I would be really cautious if they are running 1500' single run for
POE. Need to do the voltage loss calculation to be sure to use the
correct power supply.

Ive used RG8 coax in the past to deliver 24V DC to about 600ft, but not
at 1500ft. RG6 has significantly less loss over distance than 24AWG wire.

You have the best solution - regulating at the top. Otherwise, as you
state, the voltage at the top will go up when the current load goes
down. The voltage at the top will go down when the current load goes up.
MUCH better to regulate at the top...
