1.1.2 Line of Sight
The donor antenna which points towards the base station typically has a
narrow beam antenna pattern. As a result, a slight deviation away from
the direction of the BTS can lead to less than optimum results. In
addition, obstacles between the repeater and the BTS may impair the
repeater from obtaining any BTS signal. As a result, the repeater cannot
transmit signal to the coverage area. Therefore, a direct line of sight to
the BTS for the donor antenna is vital to the function of a repeater. For
the same reason, placing the server antenna in direct line of sight of the
coverage area is also necessary.
