3.2 Install GPS Antenna
WARNING:
Ensure the antenna is connected before powering up the eNB. The wireless signal
transmission power can cause bodily injury and damage to the eNB and RF power amplifier
devices.
Read the following GPS antenna installation requirements before installing it on the eNB and refer to
Figure 3-2.
No major blocking from buildings in the vicinity. Make sure the space atop is within 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.
•
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.
