If you run DC be sure and use HIPPI Grease for all wire caps or screw
terminals where termination is.

When I looked at the center pin I remember seeing like 0.001 voltage
drop at 24v and 200'. This was Nextel stuff, looks the same for all

For equivalent wire gauge would you just compare the center
conductor diameter to a wire gauge chart?

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:
