Makes sense.

Depends on the size of the heliax. The larger stuff has a tube as
center conductor. In any event just calculate the cross sectional
area of the copper of the center conductor and you can compare that
with a wire gauge chart.

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...

Thanks all, great solution Josh!

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:
