Antenna Installation Considerations

When planning site for the RF system, consider proper antennas placement.

For full instructions and guidelines, see the Motorola Standards and Guidelines for Communications

Sites, R56 manual.

RF Antenna

Place the MTS equipment near to the existing cable tray or ladder rack for RF cabling.

GPS Antenna

Mount the GPS antenna below the tallest point on the tower, pole, or roof of the MTS site.

For systems in the northern hemisphere, mount the GPS antenna to maintain a clear view of the

southern sky. For systems in the southern hemisphere, mount the GPS antenna to maintain a clear

view of the northern sky.

For more information about GPS antenna installation and cabling, see GPS Antenna Connection on

page 142

NOTICE: Each MTS in the system must be configured for the same GNSS System.

Surge Arrestors

To prevent potential damage to the MTS, install proper surge protection on all antennas.

To transport lightning strikes away from the equipment, install the lightning arrestors.

Install a lightning rod on a different tower leg than the antenna.

See Surge Arrestors and Suppliers on page 488 for more information.

3.4

Network Interface Installation Considerations

Depending on local regulations, a surge arrestor may be required at the Ethernet, X.21, or E1 service

entrance.

Choose a proper arrestor for operation with an Ethernet

, X.21, or E1 circuit and wire it according to

manufacturer instructions. The arrestor typically is only installed on the customer side of the Ethernet,

X.21, or E1 service entrance.

See Surge Arrestors and Suppliers on page 488 section in Field Replaceable Units (FRUs) on page

478 for more information.

3.5

MTS Installation Special Considerations

Special considerations includes MTS installation considerations for electrical service access,

hazardous materials, and seismic active areas.

Electrical Service Access

Adhere to the local electrical codes and regulations regarding clearance for electrical service access.
