High isolation configurations
There are four typical configurations for high isolation installations – two vertical and two horizontal.
The configurations described above are detailed in the following sections.
2.3.1 Vertical Separation Configuration
The Vertical Separation configuration is recommended in cases where the BTS is relatively far and
the service coverage area is relatively small.
In Vertical Separation configuration, the Donor antenna can be installed either above or below the
Service antenna on a COMMON tower. It is required to set the distance between them to achieve
maximum isolation. The figures below illustrate the two types of installations.

2.3.2 Horizontal Separation Configuration
In the Horizontal Separation configuration, the Donor and Service antennas are installed on two
separate towers at approximately the same height. The towers can be either on the same side of the
building or on different sides of the building as shown below.
