Chapter 3 Installing the TimeProvider
Making Connections
Prior to installing the antenna, the site, antenna location, lightning suppressor
location, cable route, and all other details should be planned. Use Figure 3-17 as a
guide to locating the antenna.
Figure 3-17. Locating the GPS Antenna
To install the antenna, refer to Figure 3-18, and perform the procedure in this
section. Ensure all user-supplied materials are available. The minimum distance
between the antenna and the shelf is 20 feet (6 m); the maximum distance between
the antenna and the shelf is 1000 feet (304 m).
Warning: To prevent arcing, ensure that the lightning suppressor is
installed away from electrical devices and cabling.
Note: Use the following antenna installation instructions as a
guideline only. Install the antenna using company-approved
techniques, and follow all appropriate local building and electrical
codes.
Recommendation: The TimeProvider uses an antenna that requires
a minimum cable length of 20 feet (6 m) from the antenna to the
TPIU. Symmetricom recommends that you adhere to this minimum
length requirement to ensure proper antenna operation.
