The pre-assembled Rox System can be used on installations with:
One, two, or three radio sectors. See Understanding radio sectors
on page 13.
If fewer than three radio sectors are used at a particular installation, the unused RF antenna cables
exiting through the Rox System cabinet seal must be connected to external surge suppression equipment
to prevent equipment damage from lightning strikes.
Redundant and non-redundant Digital Module Kits.
Redundant installations use two GPS antennas; non-redundant installations use a single GPS antenna.
(See Understanding Digital Module Kit redundancy
on page 20.) In non-redundant installations, the
secondary GPS antenna cable must be connected to external surge suppression equipment to prevent
damage from lightning strikes.
The pre-assembled Rox System cannot be used for installations that have three separate RF antenna cables
for each radio sector. In this case, you must use a specially-ordered Rox System cabinet seal with nine RF
cables.
The pre-assembled Rox System is shipped fully assembled with cables that are 8 feet long, 3/8 inch or 1/2
inch in diameter, and have male N-Type connectors at both ends. See Table 20
.
NOTE
If you special ordered a Rox System cabinet seal, or assembled it
yourself, you might have a different number of cables and
different connector types.
