## Long description

The Ubiquiti AF-11-DUP-L is a low‑band duplexer designed for use with the AF-11 radio. It provides two configurable frequency channels — a low channel (10.700–10.955 GHz) and a high channel (11.200–11.445 GHz) — selectable by reversing the duplexer position. The unit is intended to enable either single‑input single‑output (SISO) operation with one duplexer or multiple‑input multiple‑output (MIMO) operation when a second duplexer is added. The product comes in a silver and white finish and is sold individually.
Advantages
The AF-11-DUP-L offers straightforward channel selection through mechanical reversal, compact design compatible with the AF-11 platform, and the flexibility to support SISO or, with an additional unit, MIMO configurations. Its specified low and high channel ranges ensure predictable frequency splitting for deployment in the designated bands.
Suitable for
 Configuring AF-11 radios for low- or high-band operation
 Upgrading a SISO AF-11 installation to MIMO by adding a second duplexer
 Outdoor wireless backhaul setups requiring defined duplex channels

How to use
Install the AF-11-DUP-L into the AF-11 radio following the AF-11 installation instructions. Select the desired channel range by inserting the duplexer in the appropriate orientation (normal or reversed) to obtain the low or high channel. For SISO operation, fit a single duplexer. To enable MIMO, mount a second duplexer as specified by the AF-11 MIMO configuration guidelines.
Usage recommendations
Verify compatibility with the AF-11 radio and follow manufacturer torque and grounding instructions during installation. When deploying MIMO, ensure proper antenna separation and alignment per Ubiquiti guidelines to achieve optimal performance.
