Nova846 Outdoor 8x5W Two-Carrier TDD eNodeB Installation Guide
No major blocking from buildings in the vicinity. Make sure the space atop is at least
45 degrees unblocked by any buildings.
The GPS antenna should be installed within 45 degrees to the lightning rod.
Do not install the GPS antenna near other transmitting and receiving equipment, to avoid
interference. Do not install it under a microwave antenna or high voltage cable. Avoid the
direction of radiation from other transmitting antennas to the GPS antenna.
The top of the GPS antenna should not be placed in the frontal position of the eNB's
directional antenna if possible. If an obstruction occurs, it is recommended to install the GPS
antenna in an open and lightning-protected location rather than to the eNB.
When two or more GPS antennas are installed, it is recommended to keep the spacing of more
than 6.74 feet (2 meters) and install multiple GPS antennas in different locations to prevent
simultaneous interference.
GPS antenna feeders cannot be grounded together with ground conductors of interfering
equipment such as air conditioners, motors, and pump motors, etc. to prevent external
interference from being introduced into the antenna system.
Figure 3-2: GPS Installation Requirements
The GPS antenna system is assembled in manufacturing before packing. The only installation step
is to fix the GPS mounting bracket on the eNB with the M4*14 screws (Figure 3-3).
Figure 3-3: GPS Antenna Installation
NOTE: The GPS antenna models used may vary, but the installation steps are the same as
described here and shown in Figure 3-3.
