local electrical regulatory codes.
High-Band Duplexer(s) (model AF-11-DUP-H) or Low-Band Duplexer(s) (model AF-11-
DUP-L) are required for proper operation:
SISO mode: One Duplexer of either band type
MIMO mode: Two Duplexers of the same band type
(Optional) If not using PoE: DC power source and 12/30 AWG power cable
Outdoor, shielded Category 6 (or above) cabling and shielded RJ-45 connectors are
required for all wired Ethernet connections.
Hardware Overview
Note: Duplexers must be purchased separately. The Duplexer(s) must match
the terms of your license (frequency bands and polarities allowed).

LED remains lit to indicate the boot sequence is underway.
Initializing airFiber Software When the airFiber application begins to boot under
airOS®, the Signal 4 LED goes from solidly on to a 2.5 Hz ash. This continues until the
AF ‐ 11FX is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how
close the AF ‐ 11FX is to ideal aiming. This is auto-scaled based on the link range, the
antenna gains, and the congured TX power of the remote AF ‐ 11FX. Each Signal LED
has three possible states: On, Flashing, and Off. All Signal LEDs would be solidly on in an
ideal link. For example, if the link has a 1 dB loss, the Signal 4 LED will ash; a 2 dB loss
and the Signal 4 LED will turn off. The full bar graph LED states are shown below.

Installation Overview
We recommend that you congure your paired AF-11 radios before site installation. The
overview below summarizes the installation procedure, and the subsequent sections
provide detailed installation information.
Install the Duplexer(s) in the AF-11 radio.
Connect the airFiber Gigabit PoE adapter to the DATA port, and connect your computer
to the MGMT port.
Congure the AF-11.
Install a ground wire and mount the AF-11 on the airFiber AF-11G35 antenna (or a
compatible antenna).
At the installation site, install the antenna with the mounted AF-11 radio (see the
antenna’s Quick Start Guide for installation instructions).
Connect the DATA port to your LAN, and connect power (PoE or DC power) to the AF-11.
Establish and optimize the RF link.

Note: Position the low channel and high channel ports to yield the required
transmit and receive frequencies.
3.
WARNING: Tighten the collars alternately, a half turn at a time, until both are
fully tightened. Failure to do so may result in damage to the Duplexer.
4.
5. Repeat steps 1-4 for the radio to be used on the other end of the link, ensuring that the
numbers on the second radio’s Duplexer are in the reverse order of the numbers on rst
radio’s Duplexer.
Note: For example, if the numbers on the rst radio’s Duplexer are (left to right)

1/3, then the numbers on the second radio’s Duplexer should be 3/1.
Installing the Duplexers for MIMO Mode
Note: MIMO operation requires two licenses, one per polarization and two
Duplexers of the same band type.
1.
2.
Note: Position the low channel and high channel ports to yield the required
transmit and receive frequencies. Also, ensure that the numbers on the right-
side Duplexer are in the reverse order of the numbers on the left-side Duplexer.
3.
WARNING: Tighten the collars alternately, a half turn at a time, until both are
fully tightened. Failure to do so may result in damage to the Duplexer.
4.
5.
6. Repeat steps 1-5 for the other radio to be used in the link, ensuring that the numbers on
the second radio’s Duplexers are in the reverse order of the numbers on the rst radio’s
Duplexers.
Note: For example, if the numbers on the rst radio’s Duplexers are (left to right)
2/4 and 4/2, the numbers on the second radio’s Duplexers should be 4/2 and 2/4.

3. At the installation site, secure the other end of the ground wire to a grounded mast,
pole, tower, or grounding bar.
WARNING: Failure to properly ground your airFiber radio will void your
warranty.
Note: The ground wire should be as short as possible and no longer than one
meter in length.
Mount to the airFiber AF-11G35 Antenna
1. Attach an RF Cable to an RF connector labeled H or V. Then slide the silicone boot over
the RF connector to protect it.
If using MIMO mode, remove the cap over the second RF connector (V or H) and attach
an RF Cable. Then slide the silicone boot over the RF connector to protect it.

Follow the instructions for the source of power that you are using: Power over Ethernet or
DC Power.
Power Over Ethernet
WARNING: Use only the included adapter, model POE-50-60W. Failure to do so can
damage the unit and void the product warranty.
DC Power
1. Connect a DC power cable to the Terminal Block. (The +VDC and GND can be
connected to either terminal.)
2. Connect the other end of the DC power cable to a DC power supply that supplies
+50VDC.
WARNING: Applying a negative voltage such as -48VDC will damage the radio.
3. Connect the DC power supply to its source.
Surge Protection
For added protection, install two surge suppressors, such as the Ubiquiti Ethernet Surge
Protector, model ETH-SP-G2, at the end of each link. Install the rst surge protector within
one meter of the airFiber DATA port, and install the second surge protector at the ingress
point of the location housing the wired network equipment.
Alignment
Tips
To accurately align the airFiber 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 signicant elevation differences between
airFiber radios.
Establishing a Link
Adjust the positions of the Master and the Slave to establish a link. The following section
features the airFiber X antenna, AF-11G35:
Note: The Master must be aimed rst 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, adjust the
azimuth and the elevation.
Adjust the azimuth:
a. Loosen the four ange nuts on the two pole clamps.
b. Rotate the antenna to point towards the other end of the link.
c. Tighten the four ange nuts on the two pole clamps.
Adjust the elevation angle:
a. Loosen the eight hex head bolts to so that the washers can spin freely by hand.
b. Tighten or loosen the Elevation Adjustment Bolt to set the desired tilt.
c. Tighten the eight hex head bolts.
Note: Do NOT make simultaneous adjustments on the Masterand Slave.
2. Slave Visually aim the Slave at the Master. To adjust the Slave’s position, adjust the
azimuth and elevation as described in step 1.
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 the Signal LEDs section 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 airFiber radios.
7. Lock the alignment on both airFiber antennas by tightening all the nuts and bolts.
8. Observe the Signal LEDs of each airFiber 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, nalize the alignment of each airFiber antenna again,
and retighten the nuts and bolts.
