Neutral bar is in the circuit breaker panel. It is where all the white wires terminate. You attach, clamp, solder a white wire to the shield. Extend the insulated center conductor and put it on a circuit breaker. Instant $120 VAC appears at the top of the tower. Depending on the size of the coax, you could easily do 30 amps or more.

AC -> battery charger -> 24v batteries -> coax up the building coax -> 24v regulator -> PacketFlux What is the neutral bar?

Why not just tie the center conductor to a circuit breaker and make sure the shield is tied to the neutral bar. Then you have all kinds of options up there. From: Josh Luthman via Af Sent: Monday, November 10, 2014 9:20 AM To: af@afmug.com Subject: [AFMUG] New site DC power help I am getting onto a new site that is a building. The owner has given me free permission to use anything I want that Sprint left. That's the nice building as well as 6 heavy duty >1" thick coax runs from the base to the top of the tower. What I would like to do is run DC on one of these. They have connectors that look twice as big as N connectors. How can I go from this connector to a DC power supply? What about at the top from the coax to a regulator? Am I correct in assuming the center pin would be hot and the outside/threading be neutral? Would 24vdc be OK for this? Or would 48vdc be better? Thanks in advance for any help! I'd like to avoid running 10 feet of wire and soldering if at all possible.
