Low space in the tower
Armour with a strong skeleton
When installing the antennas there are 2 things to consider, the first is that there is very little space on the tower which generates interference from the antennas themselves due to the small separation, the second is that the capacity of the radios modulated better by isolating the internal noise of the tower itself, as well as the same way we proceeded to make a second fine tuning as the antenna became more directive in its firing beam.
