Ubiquiti AF-11-DUP-L airFiber Low-Band Duplexer
Overview
The Ubiquiti AF-11-DUP-L is a low-band duplexer designed for use with the airFiber AF-11 licensed backhaul radio. It provides the low-band frequency configuration required for compatible AF-11 deployments within the 11 GHz licensed frequency range.
The AF-11 uses a modular duplexer design, allowing its frequency configuration to be changed according to the required licensed band. The AF-11-DUP-L can also be used as the second duplexer when configuring an AF-11 radio for MIMO operation.
Frequency Channels
The AF-11-DUP-L provides a low channel range of 10.700–10.955 GHz and a high channel range of 11.200–11.445 GHz. The duplexer can be positioned within the AF-11 to provide the required transmit and receive frequency arrangement.
| Channel | Frequency Range |
|---|
| Low Channel | 10.700–10.955 GHz |
| High Channel | 11.200–11.445 GHz |
Compatibility
The AF-11-DUP-L is specifically designed for the Ubiquiti AF-11. Ubiquiti specifies one duplexer of either band type for SISO operation and two duplexers of the same band type for MIMO operation.
Duplexer selection must correspond to the frequency bands and polarities permitted by the applicable wireless license.
MIMO Configuration
The AF-11-DUP-L can be used as the additional low-band duplexer required for an AF-11 MIMO configuration. Ubiquiti specifies that the second duplexer is purchased separately.
Installation
The duplexer installs directly into the compatible AF-11 radio. Ubiquiti's AF-11 installation documentation specifies installing the duplexer before connecting the radio to the antenna and configuring the wireless link.
The duplexer position determines the low and high channel arrangement. Frequency and polarity settings should be configured according to the AF-11 documentation and the applicable license.

FAQs
What is the Ubiquiti AF-11-DUP-L?
The AF-11-DUP-L is a low-band duplexer designed for the Ubiquiti airFiber AF-11 licensed backhaul radio.
Which radio is compatible with the AF-11-DUP-L?
Ubiquiti specifies the AF-11 as the compatible radio.
What frequency ranges does the AF-11-DUP-L support?
The low channel covers 10.700–10.955 GHz, while the high channel covers 11.200–11.445 GHz.
Can the AF-11-DUP-L be used for MIMO?
Yes. Ubiquiti specifies two duplexers of the same band type for AF-11 MIMO operation, so a second AF-11-DUP-L can be used for a low-band MIMO configuration.
Is the duplexer included with the AF-11?
The AF-11 includes one duplexer for SISO operation. A second duplexer required for MIMO operation is purchased separately.
Is the AF-11-DUP-L a complete wireless radio?
No. It is a separately purchased duplexer accessory for the AF-11.
