Installation Overview
- Configure paired AF-11 radios before site installation.
- Install the Duplexer(s) in the AF-11 radio.
- Connect the airFiber Gigabit PoE adapter to the DATA port and your computer to the MGMT port.
- Configure 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.
- Connect the DATA port to your LAN and connect power (PoE or DC power).
- Establish and optimize the RF link.
Installing the Duplexers
For SISO Mode
- Remove the duplexer cap from the AF-11 radio.
- Align the Low-Band or High-Band Duplexer with the SMA ports (TX 0, RX 0).
- Connect the duplexer by pushing it down onto the SMA ports and tightening the collar. WARNING: Tighten collars alternately, a half turn at a time, until fully tightened to prevent damage.
- For the second radio, repeat steps 1-4, ensuring the numbers on the second radio's Duplexer are in the reverse order of the first radio's. (e.g., if first is 1/3, second should be 3/1).
For MIMO Mode
- Remove the duplexer caps from both sets of SMA ports.
- Align and attach one Duplexer to the first set of SMA ports (e.g., TX 0, RX 0).
- Align and attach the second Duplexer to the second set of SMA ports (e.g., TX 1, RX 1).
- Ensure the low channel and high channel ports are positioned correctly for transmit and receive frequencies.
- WARNING: Tighten collars alternately, a half turn at a time, until fully tightened.
- For the second radio, repeat steps 1-5, ensuring the numbers on the second radio's Duplexers are in the reverse order of the first radio's. (e.g., if first is 2/4 and 4/2, second should be 4/2 and 2/4).
Connecting Power over Ethernet (PoE)
- Connect an Ethernet cable from the airFiber Gigabit PoE adapter's Ethernet port to the AF-11's DATA port.
- Connect the Ethernet cable from the PoE adapter's other Ethernet port to your LAN or switch.
- Connect the power cord to the PoE adapter and plug it into a power outlet. WARNING: Use only the included adapter, model POE-50-60W. Failure to do so can damage the unit and void the product warranty.
airFiber Configuration
- Configure your computer's Ethernet adapter with a static IP address on the 192.168.1.x subnet (e.g., 192.168.1.20).
- Launch a web browser and navigate to https://192.168.1.20.
- Log in using username 'ubnt' and password 'ubnt'. Select your Country and Language, and agree to the Terms of Use.
- Basic Wireless Settings:
- Set Wireless Mode to Master for one AF-11 and Slave for the other.
- Enter a Link Name (must be the same for both).
- Adjust Channel Bandwidth, Output Power, and Maximum Modulation Rate if needed.
- Frequency Settings: Configure TX Frequency and RX Frequency. Ensure they are reversed between the Master and Slave units.
- Wireless Security: Select Key Type (HEX or ASCII) and enter the Key.
- Click Save Changes.
- Network Settings: Ensure each AF-11 has a unique IP Address. Access the Network tab. For Management IP Address, choose DHCP or Static and configure accordingly. Click Save Changes.
- Disconnect Ethernet cables. Repeat configuration for the second AF-11.
- For detailed information, refer to the airFiber AF-11FX User Guide at ui.com/download/airfiber.
Hardware Installation
Install a Ground Wire
- Attach a ring terminal to a 10 AWG / 5 mm² ground wire.
- Secure the ring terminal to the grounding screw on the AF-11 radio.
- 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. The ground wire should be as short as possible, no longer than one meter.
Mount to the airFiber AF-11G35 Antenna
- Attach an RF Cable to an RF connector labeled H or V on the duplexer. Slide the silicone boot over the RF connector. For SISO mode, use the connector determined by licensing and cover the other with the metal cap. For MIMO mode, attach RF cables to both H and V connectors.
- Align the dot on the side of the shroud with the arrowhead on the dish antenna.
- Attach the AF-11 radio to the antenna mount.
- Connect the RF cables from the duplexers to the corresponding ports on the AF-11 radio. Ensure proper alignment and tighten the connectors.
Connecting Data
- Connect an Ethernet cable from the AF-11's DATA port to your LAN or switch.
- If using DC power, connect the other end of the Ethernet cable to your LAN.
Connecting Power
Power Over Ethernet
Connect the airFiber Gigabit PoE adapter to the DATA port, then connect the adapter to your LAN and a power outlet. WARNING: Use only the included adapter, model POE-50-60W.
DC Power
- Connect a DC power cable to the Terminal Block (+VDC and GND).
- Connect the other end of the DC power cable to a +50VDC power supply. WARNING: Applying a negative voltage will damage the radio.
- Connect the DC power supply to its source.
Surge Protection
Install two surge suppressors (e.g., Ubiquiti Ethernet Surge Protector, model ETH-SP-G2) at each end of the link. Install one within one meter of the airFiber DATA port and the second at the ingress point of the wired network equipment location.
Alignment
Tips
- Align only one end of the link at a time.
- Additional hardware may be needed for mounting pole orientation or elevation differences.
Establishing a Link
Adjust the positions of the Master and Slave to establish a link. Aim the Master first.
- Master Alignment: Visually aim the Master at the Slave. Adjust azimuth by loosening pole clamp nuts, rotating the antenna, and tightening nuts. Adjust elevation by loosening hex head bolts, adjusting the Elevation Adjustment Bolt, and tightening bolts. Note: Do NOT make simultaneous adjustments on Master and Slave.
- Slave Alignment: Visually aim the Slave at the Master. Adjust azimuth and elevation as described for the Master.
- Check if a link is established: LINK LED should be solidly lit green, and Signal LEDs should show signal levels.
- Fine-tune alignment: Aim the Slave at the Master for the strongest signal on the Master. Then, aim the Master at the Slave for the strongest signal on the Slave. Repeat until all four Signal LEDs are solidly lit for optimal data rate.
- Lock alignment: Tighten all nuts and bolts. Observe Signal LEDs during tightening; if values change, readjust and retighten.
