FT-512 Trailblazer Installation and User Manual version 1.08 35
Final alignment is performed by connecting a standard telephone directly to the
subscriber (FXS) wide and listening to the dial tone. As the antenna (device
housing) is moved to the left the signal will degrade, the bit error LED will flash,
and eventually the link will be lost. Noting where the antenna is aimed when the
link is lost the antenna is then rotated to the right until the same dropout is
experienced. The antenna is then located in a final position which is midway
between these points. Due to the 33 degree beam width of the antenna this
method of alignment is more than sufficient to ensure proper alignment.
