Antenna Cable Choices
Antenna Cable Choices
The antenna assembly uses the same coaxial cable for power and antenna signals.
The length of cable is determined by circumstances of the installation and site.
Two cables are required: one to connect the antenna to the lightning suppressor,
and another to connect the lightning suppressor to the TimeSource 3100 Shelf.
