This stuff looks pretty freakin cool...

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.
