Positioning a Directional Antenna
ENGLISH
When you are using LEDs to maximize the signal, adjust the antenna until as many LEDs as possible are
on and the rest are blinking as fast as possible. With all three LEDS on, the signal is good enough to
support the maximum data rate.
on and the rest are blinking as fast as possible. With all three LEDS on, the signal is good enough to
support the maximum data rate.
To position the antenna using the LED indicators, follow these steps:
Step 1
Verify that the Install LED is either continuous amber or green.
Step 2
Slowly pan the bridge to the left and right of the signal path, and watch for peaks in signal strength. Be
sure to swing the antenna in an arc of 60 degrees to each side to ensure that the integrated antenna passes
through the main and side lobes of the remote antenna.

Step 3
Return the bridge to the position where the signal is strongest, or in the case of two similar peaks,
halfway between them.
halfway between them.
Step 4
Secure the horizontal adjustment by tightening the U bolts on the mast. Torque the nuts to 6 to
8 ft-lb.
Step 5
Slowly tilt the bridge up and down, and watch for peaks in signal strength. Use the full vertical
adjustment range of the mounting brackets.

Step 6
Return the bridge to the position where the signal is strongest, normally where all signal strength LEDs
are on. If you are unable to turn on all LEDs, simply maximize the signal.

Step 7
Secure the vertical adjustment by tightening the four bolts that secure the housing bracket to the support
