2.2.2.3 Hoisting Grips
Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable
without damaging the cable. Each hoisting grip is capable of safely lifting 200 feet of
cable without causing damage. Therefore, one hoisting grip is required for every 200-foot
section of cable. The grips may be left attached to the cable after the cable installation is
completed.
Some situations may require more hoisting grips, such as:
• An installation to a tower which is on top of another structure.
• Any installation where the length of cable that must be lifted is greater than the
height of the tower.
In these situations, additional hoisting grips should be ordered.
WARNING
Under NO conditions should RF connectors be used to attach a rope or cable.
2.2.2.4 Hangers and Adapters
Coaxial cables on the tower should be secured at intervals of 3 feet (maximum).
Securing 7/8-inch and 1 5/8-inch diameter coaxial cables is accomplished by using either
hangers or hanger-adapter combinations. The hangers secure the cables to the tower
structure by using prepunched holes or attachment adapters.
When the tower structure is prepunched with 3/4-inch holes, snap-in hangers are used
(preferred method).
When the tower is prepunched with 3/8-inch holes, the hanger is secured by a 3/8-inch
bolt.
For towers without prepunched holes, the hangers are attached with adapters. The type of
adapter depends on the type of tower structure. Adapters are available for either angle
tower members or round tower members.
