Securing
It is vital that runs of flex cable be secured firmly at frequent intervals. This is done to prevent mechanical damage from cables rubbing against each other and tower members.
Precautions
 |
When securing cables, care must be taken not to crush or deform the outer conductor of the cable. |
Procedure
To prevent mechanical damage, cables should be secured any time they pass within 4 inches of each other or a tower member.
Cable runs longer than the following should be secured. These are approximate; secure to tower members as actually available.

* Recommended per flex cable manufacturer.
Various hangers and clamps are available from various sources for securing cable. Shively will supply cable clamps ("butterfly clamps") with your antenna in a quantity based on our best guess of your needs - but every tower and installation is unique! Therefore, additional cable clamps as required and round and angle tower member clamps should be supplied by your rigger.
 |
Shively will not be responsible for installations that don't meet our recommendations! |
- Cable to Flat, Round, or Angle Tower Member:
- Use hangers and hose clamps, as shown on the enclosed sheet, to secure the cable.
- Cable to Cable:
- Use two cable clamps and a full-threaded bolt or threaded rod with nuts, as shown in figure 1 of this sheet, to secure the cables together.
