Real case 2: Oscillation caused by signal reflection
Basic information description
1. The outdoor antenna is right facing the
cell tower;
2. There is a big building infront of the
outdoor antenna, about 100 ft away from
the outdoor antenna;
3. Distance between the indoor and
outdoor antenna is good enough;
4. Indicators for band 12 and band 13 on
the panel always solid green after power
on. Other band indicators flash.
Case analysis:
The outer surface of the building facing the
outdoor antenna, become a big reflect
surface. It reflect the signal from the outdoor
antenna to the indoor antenna.
Solution:
Vertical rotating outdoor antenna up 15 to 30 degree. Keep the cell tower at the
bottom edge of the main beam, same time move part of the opposite building out of
the main beam. This reduces the energy of the reflected signal.
