It is far easier to surge protect raw power than any data circuit. I'm not saying I wouldn't deploy something less than my ideal, but someone's gotta keep beating the manufacturers until they do it.

Yes, a more weak point is always going to be a copper ethernet PHY. However, I will say that our loss rate at towers has significantly gone down after moving to DC UPS's, fuses (PacketFlux solid-state even better) and better surge suppressors. Would I like to completely get rid of POE, absolutely. I completely support Mike's call for SFPs. Problem is, most vendors still view that as a way to make more money. They hold it over our heads claiming the carrier grade argument. While others claiming carrier grade are nowhere near "carrier grade". And some even make you buy a license key to use the slot(s).

Which is nice because most licensed radios for example have a dedicated 10/100 copper management port.

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. ------ Original Message ------ From: "Craig Schmaderer" < cr...@skywaveconnect.com > To: mailto:email@example.com < firstname.lastname@example.org > Sent: 9/16/2016 5:24:43 PM Subject: [AFMUG] DC tower cable bundle <blockquote> 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.
