Hi Frank: Don't know of any "Professional" riggers that use that
method, and would be suspicious if I saw them. Pros use coax
hangers to properly hang coax and waveguide.
It is too easy to cause dimpling with anything that wraps around
the coax and a leg. (Tye-Wraps included.)
The better method, if hangers are too spendy for the install, would
be the "Tower-Tape" that DB Products sells. It is a UV protected
filament tape, but only good for a couple of years if unprotected.
On budget jobs, I use the Tower-Tape every 15 inches or so and then a
wrap of Scotch 88 over it. The scotch bonds well enough with the
filament to last a long time.
