[TowerTalk] Coax and cable loop at antenna

[Frederick Mott]

I installed 2 runs of 7/8 helix cable on the inside of my tower and I used
SS cable ties.  Plastic ties (I don't know of any good UV protected plastic
ties) will rot away after a few years of sunlight.  As far as your cable
length, add enough cable to  make a loop between the tower and your antennas
so that the cables will not be stressed.  Use your judgment or better yet
buy some good antenna and or tower books/publications from the ARRL.

How do you figure out how much coax and control cable to put between your
rotator and the antenna?

How do you secure those cables on both the tower side and at the antenna?

What kind of coax do you use there? BuryFlex or something else?

I'm also looking for a good way to secure cables to the outside of the
tower. I'm not using a Rohn-style with multiple smaller support posts.
Instead, it's a single pole, 220mm in diameter. I'm reluctant to just use
long plastic cable ties. Is there a better approach?
