Alignment
Tips
• To accurately align the airFiberX 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 airFiberX radios.
Note: If you have AF-5X radios mounted in an
airFiber Multiplexer (AF-MPx4 or AF-MPx8),
perform the procedure in “Establishing a Link”
on page9 on one radio only. This will help
ensure maximum success in registrations. Refer to
“AF-5X and airFiber Multiplexer” on page 45
for additional information on airFiber Multiplexer
installation.
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.
Note: The airFiber X antenna AF-5G30-S45 is
shown in the following steps. Instructions for other
antennas are similar. For complete details, refer to
the Quick Start Guide for your specific model.
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.
b. Loosen the six elevation bolts, and use the hex nut
on the elevation rod to adjust the elevation.
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.
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 airFiberX radios.
7. Lock the alignment on both airFiber antennas by
tightening all the nuts and bolts.
8. Observe the Signal LEDs of each airFiberX 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.

The following applies to the AF-5X only:
When the AF-5X operates in a DFS country and within a
valid DFS band for that country, it performs a Channel
Availability Check (CAC) before operating. The rules vary
by country and frequency, but in general:
- FCC domains If the AF-5X operates in a DFS band
(5.2GHz or 5.4GHz band), the AF‑5X performs a
60-second check on the Masteronly.
- ETSI domains For most frequencies, the AF-5X
performs a 60-second check on the Master and Slave;
however, if it operates in the 5600‑5650 MHz range,
then the AF-5X performs a 10-minute check.
While the AF-5X is performing this check, the RF Link
Status displays DFS CAC, and the RF Link Timeout is
displayed.
If radar is detected, the RF Link Status displays RADAR
Detected, and the RF Link Timeout is displayed.
RF Link Timeout (Available only if the RF Link Status
is DFS CAC or RADAR Detected.) During the DFS CAC or
RADARDetected state, the RF Link Timeout counts down
the time remaining before the airFiberX radio can move
to the next RF link state.
