If your fiber does not have a metal armor/messenger in it, you can run it with the 120v. You might consult an electrician, but I'd probably run the single mode fiber and 3 conductors of thwn electrical wire into a bundle, terminate the fiber for the top end, hoist it up, chop the bottom of the bundle, and slide plastic conduit up the tower with the wire in place, 100' at a time. Fasten the conduit to the tower at appropriate intervals. Have an electrical box every 100' with something to take the strain off the wire.
Tried it once with 300' of wire/fiber/liquitight all at once, and it was more weight than we were prepared to handle. The wire slipped irretrievably back into the liquitight, we dropped some of the liquitight and it damaged itself from the stretching. We ended up with a big scrap pile of the stuff for small jobs. Now, we just use POE, but that wasn't an option ten or more years ago. We don't use any towers so high we can't do POE. The concept of 120v on a tower isn't unusual. Most of the lighting systems are probably 120/240. On Sat, Aug 07, 2010 at 11:23:01PM -0400, RickG wrote: > Nice!
