3. Master Aim the Master at the Slave . If necessary, adjust
the Master ’s position on the pole:
a. Loosen the Hex Nuts .
b. Adjust the Pole Mount Bracket and Pole Clamps .
c. Tighten the Hex Nuts .

4. Slave Listen to the audio tone of the Slave – the higher
the pitch, the stronger the signal strength. Aim the
Slave at the Master to achieve the strongest signal
strength. If necessary, adjust the Slave ’s position on
the pole.
5. Master Adjust the azimuth and elevation of the Master
until you hear the highest pitch for the Master .
a. Sweep the Azimuth (AZ) Adjustment Bolt of the
Master through its adjustment range.

Fine-Tuning the Link
The Azimuth (AZ) and Elevation (EL) Adjustment Bolts of
the Alignment Bracket adjust the azimuth and elevation
within a range of ±10°. For accurate alignment, make
adjustments on one end of the link while the other
installer listens to the audio tone at the other end of the
link. Do NOT make simultaneous adjustments on the
Master and Slave .
1. Slave Adjust the azimuth and elevation of the Slave
until the other installer hears the highest pitch for the
Master .
2. Master Adjust the azimuth and elevation of the Master
until the other installer hears the highest pitch for the
Slave .
3. Repeat steps 1 and 2 until you achieve a symmetric
link, with the received signal levels within 1 dB of each
other. This ensures the best possible data rate between
the airFiber radios.
Note: If you have difficulty discerning whether the
link is symmetric, you can use one of the following
methods to determine more precise received
signal level readings.
• LED Display (See
“Using the LED Display” on
page 13
.)
• airFiber Configuration Interface (See “Using
the airFiber Configuration Interface” on
page 15
.)
4. Lock the alignment on both airFiber radios by
tightening all eight Lock Bolts on the Alignment Bracket.
Listen to the audio tone for each airFiber AF-24 to ensure
that the value remains constant while tightening the
Lock Bolts . If the audio tones change during the locking
process, loosen the Lock Bolts , finalize the alignment of
each airFiber AF-24 again, and retighten the Lock Bolts .
