2.5.3 Grounding
The Duo-i6525 has locks on the side of the enclosure preventing from the door
opening. In addition, a ground cable is also included in the box and should be
connected to repeater.
2.5.4 Antenna Separation/Isolation
Separation between antennas is necessary to prevent oscillation.
Oscillation occurs when the signal entering the system continually reenters,
due to the lack of separation between the donor and server antennas. In
other words, the signal is being fed back into the system. This creates a
constant amplification of the same signal. As a result, the noise level rises
above the signal level.
