1 Pan the antenna horizontally back and forth while checking the LEDs. If using
the pole-mounting bracket with the unit, you must rotate the mounting
bracket around the pole. Other external antenna brackets may require a
different horizontal adjustment.
2 Find the point where the signal is strongest (all LEDs on) and secure the
horizontal adjustment in that position.
NOTE: Sometimes there may not be a central lobe peak in the voltage because
vertical alignment is too far off; only two similar peaks for the side lobes are
detected. In this case, fix the antenna so that it is halfway between the two
peaks.
3 Loosen the vertical adjustment on the mounting bracket and tilt the antenna
slowly up and down while checking the LEDs.
4 Find the point where the signal is strongest and secure the vertical adjustment
in that position.
