Especially true if you're colo'd with high powered transmitters.

That doesn't do much for me. I don't want any copper data plugged into my infrastructure. It's another weak point. Yes, I want OOB management, but I don't want copper data.

Power + fiber is cool and all, but the 1246 brings a cat6 with it. Which is nice because most licensed radios for example have a dedicated 10/100 copper management port.

Superior Essex sells a 16/2 and a 16/4 with outdoor jacket for use on towers.

You could also run a higher gauge wire that will carry the necessary total amperage and split it at the top with terminal blocks. You might need something burly for that, like for four Telrad 1000 BTS's at 100watts each you'd want at least 6ga THHN going up in a 1/2" conduit, and you'd have around 5% heat loss at 100m. But that's a smaller footprint on the tower than 16/4 x 4, or 16ga THHN x 16.

My quick figuring with home depot prices says it's cheaper to run the pair of 6ga than to run a bundle of 16ga. If you bump up to 4ga it's still cheaper than running all 16's, but by less margin. The downside of course is that you can't power cycle an individual unit, and maintenance (like replacing DC SS) would affect everything instead of just the one unit.

If you did run one big cable up, you'd still need individual outdoor jacketed cables to branch out to the base stations.

I'm not sure of the cost difference vs Superior Essex, but I've also seen outdoor speaker wire at 16ga.

Looking for advice on what my options are for running 16 DC conductors around 16 awg to power LTE and/or medusa radios on a tower. Hybrid fiber option would be ok too. I know I have seen Verizon on some of our towers use the hybrid cables. Thanks, Craig.
