2.3.5 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.
