It is pretty easy to insert and remove power from a coax that also has RF on it
too. Just a choke coil and capacitor at both ends. If you want details give
me the frequency and what kind of power and I will design it for you.

Yep .we used. LMR 400 to power custom made receive amps for WMux radios we
modified long time ago.

Just make sure if you hook it up to 120 VAC main current you don’t put the
hot wire on the outer conductor of the coax...

You can run DC or AC over it.
Think of it this way, 1000 watt ham radio puts 223 volts AC (at RF
frequencies) on the coax and everything is just fine.
All CATV systems put 60 or 90 volts AC on the line to power the amps.

Any reason I couldn't use 1/4" heliax I already have in place up a tower to
run power to a POE switch?
This is the stuff:
