Factors to take into consideration when choosing a cable are:
•
price;
•
bend radius limitations (the lower performance cables generally can
bend more sharply)
•
performance requirements; and,
•
distance between the equipment and the antenna.
When installing the cable, always begin fastening at the top near the antenna
connector/surge arrestor. The cable must be supported at the top with a hose
clamp or wrap lock, and at 5 ft intervals down the length of the tower. Over-
tightening the fasteners will dent the cable and reduce performance. If
properly grounded surge arrestors are not installed at both the top and the
bottom of the cable, then the cable should be grounded to the tower at these
locations using a cable grounding kit. If the tower is non-conductive, then a
separate conductor, physically separate from the cable, should be run down
the tower.
