Establishing a Link

Adjust the positions of the Master and the Slave to
establish a link.

Note: The Master must be aimed first at the Slave

because the Slave does not transmit any RF signal
until it detects transmissions from the Master.

1. Master Visually aim the Master at the Slave. To adjust
the Master’s position:

a. Loosen the four pole clamp nuts, and rotate the

airFiber antenna on the pole to align the azimuth.

Alignment

Tips

• To accurately align the airFiberX radios for best

performance, you MUST align only one end of the link at
a time.

• You may need to use additional hardware to

compensate for issues such as the improper orientation
of a mounting pole or significant elevation differences
between airFiberX radios.

b. Loosen the six elevation bolts, and use the hex nut

on the elevation rod to adjust the elevation.

Ubiquiti Networks, Inc.

Note: Do NOT make simultaneous adjustments

on the Master and Slave.

2. Slave Visually aim the Slave at the Master. To adjust the

Slave’s position:

a. Loosen the four pole clamp nuts, and rotate the

airFiber antenna on the pole to align the azimuth.

b. Loosen the six elevation bolts, and use the hex nut

on the elevation rod to adjust the elevation.

3. Check to see if a link is established. Ensure that the LINK
LED is solidly lit green and the Signal LEDs of the Slave
are displaying signal levels.

4. Slave Aim the Slave at the Master to achieve the
strongest signal level on the Master.

Note: Refer to “Signal LEDs” on page 2 for

details on the signal values.

Installer Compliance Responsibility

Devices must be professionally installed and it is the
professional installer’s responsibility to make sure the
device is operated within local country regulatory
requirements.

The Output Power, Antenna Gain, Cable Loss, and Frequency

fields are provided to the professional installer to assist in
meeting regulatory requirements.

Note: Maximum signal strength can best be

achieved by iteratively sweeping through both
azimuth and elevation.

5. Master Aim the Master at the Slave to achieve the
strongest signal level on the Slave.

6. Repeat steps 4 and 5 until you achieve an optimal link,
with all four Signal LEDs solidly lit. This ensures the best
possible data rate between the airFiberX radios.

7. Lock the alignment on both airFiber antennas by
tightening all the nuts and bolts.

8. Observe the Signal LEDs of each airFiberX radio
to ensure that the values remain constant while
tightening the nuts and bolts. If any LED value changes
during the locking process, loosen the nuts and bolts,
finalize the alignment of each airFiber antenna again,
and retighten the nuts and bolts.
