The AF-11-DUP-H is a high-band duplexer for use with the AF-11.
Each duplexer has a low channel (10.940 – 11.200 GHz) and high channel (11.440 – 11.700 GHz) that can be configured by simply reversing the position of the duplexer. A single duplexer operates in SISO mode, while adding a second duplexer allows the AF-11 to operate in MIMO mode.
