I feel it necessary to say that I DID tie off my coax
at each coax arm on my former crank-up (72 footer, 4
sections). It's not rocket science to get it right.
Each arm had a small coax loop to allow a
little "slop" in the measurements. Advantages include
less strain (OK, it's not THAT important) on the top
tape/tie job (and the coax in its vicinity), less
chance for snags on the way up or down (all coax
moving up and down is already airborne), and no coil
of coax on the ground to have to move/mow around.
