I'm putting a Glen Martin 4-1/2 foot tower on the peak ridge of a composition roof surrounded on all four sides by eaves and gutters extending 2 feet past the walls of the home.
That is to say, to get coax, rotor cables, the ground wire etc. off the roof they must either pass over the gutters or through the eave.
Over the gutters can be done (A current thread addresses a workable technique for this). This will certainly work but could be a visual mess and requires the wires to re-curve back to the building wall to be routed to ground and/or shack.
Through the eave cable passage can be accommodated by a flashed, short plastic pipe (like vent pipe) extending a few inches above and below the roof surface. I envision doing separate passages for the tower ground and coax/control cables.
I'd prefer the through-the-eave method because it would give me a better run for the ground wire, as well as being more aesthetically satisfactory.
I've studied over the NEC quite a bit lately, and section 810.21(G) explicitly allows a ground wire to pass inside or outside a building. http://ecmweb.com/code-basics/article-810-radio-and-television-equipment
gives a good synopsis of NEC 810. There are others.
So, while I'm not crazy about the idea of passing the ground wire through the eave it seems workable, and in this situation, preferable to the over-the-gutter method.
What would you do in this situation, and why?
