Macro Base Station Installation Procedures (NPM-1000)
 To install the main and diversity antennas
1 Verify that you have the right type of antennas, both in terms of frequency and direction.
2 Run the antenna cable from the racks to the intended location of each antenna. See your field
engineering package and installation MOP for antenna cable specifics.
NOTE: Ensure that the cable remains clear of any sources of potential interference,
such as transmitting equipment or power lines.
3 Attach each antenna to your tower or building using the required mounting hardware.
4 Orient each antenna to the correct azimuth (direction) and tilt. See your field engineering package to
determine the antenna’s correct orientation.
5 Tighten and secure each antenna.
6 Connect the antenna to the RFSS module:
i Install each TMA within 3 m (10 feet) of its antenna. The TMAs should be installed as close to
the antennas as possible in order to ensure optimal performance. Consult the documentation
that ships with the TMA for the correct mounting procedures.
ii Connect the ANT port on each TMA to its antenna using a suitable coaxial cable. Torque each
7/16 DIN connector to 17 foot-pounds and ensure each connector is properly weatherproofed.
iii Install each bias tee (also called a CIN) inside or outside the base station building, as specified
in your field engineering package. Connect the ANT port on each bias tee to the BTS port on
each TMA. Torque each 7/16 DIN connector to 17 foot-pounds and ensure each connector is
properly weatherproofed.
iv Connect the BTS port on each bias tee to the ANT port on each RFSS module. The ANT port is
located on the rear side of the RFSS module.
v Connect the CIN port (also called Vout) on the rear side of the RFSS module to the DC port on
the bias tee.
!
CAUTION: Failure to orient the antennas according to the specifications listed in
the installation MOP may seriously affect the performance of your wireless network.
!
CAUTION: Do not over-tighten connectors. Overtightening the connectors may
damage the cable and degrade the RF signal.
