So I take it that running it down the length of the tower is a bad thing, even if separated? I've got to get it down from the roof top tower to the roof and then across a gutter.
Running it down the tower is OK if it is separated
- you just don't want to tape it to
the tower legs as you would with coax. Use PVC pipe to space it out from the tower
leg. (One approach is to take a PVC T connector and slice off the back so it fits
against the tower leg and secure it with hose clamps, then stick the pipe in the
remaining opening that is now horizontal.)
Crossing a gutter shouldn't be a problem with a couple inches of clearance. Just
don't lay it in the gutter for any distance.
