Round here the pro installers seem to use elaborately spaced patterns
of insulating tape, presumably so they can differentiate their own
****-ups from competitors' ****-ups without breaking out the ladders?
Maybe not. Securing (especially foam or semi-airspaced) coax with tape,
cable ties, clips can cause slight crushing. This makes the cable very
slightly capacitive at these points, and if it is done at regular
intervals, each slight mismatch can add up and cause a suckout. So maybe
the professionals are simply demonstrating their 'professionalism' by
avoiding even the slightest possibility of the performance of their
installation being impaired?
Nah.
