INSTALLATION CHECKLIST
⚫
Working space available for installation and maintenance for each mounting arrangement. Ensure unrestricted
airflow.
⚫
Ensure earth ground point is within reach of the ground wire.
⚫
Ensure a power source is within reach of the power cord and the power source has sufficient capacity.
⚫
Where appropriate, ensure unused RF connectors are terminated.
⚫
Do not locate the equipment near large transformers or motors that may cause electromagnetic interference.
⚫
Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
⚫
Ensure VSWR of antennas system < 1.5:1.
⚫
Ensure equipment will be operated within the stated environment (see datasheet)
⚫
Observe handling of all cables to prevent damage.
⚫
Donor antenna should have a narrow beamwidth and positioned in line-of-sight (LOS) to the
donor BTS site so that
the donor signal level is maximized. This allows the use of minimum gain to achieve the maximum DL output power.
The UL gain is typically set lower than or equal to the DL gain to minimize noise interference to the donor BTS
⚫
Service antennas should be selected based on the type of service area, e.g., indoor antenna for indoor applications,
and panel antenna for outdoor applications.
