(Check your local/regional regulations for the allowable antenna gainallowed for your application.)See the antenna’s Quick Start Guide for antennainstallation instructions.Other Requirements• Clear line of sight between airFiber X radios• Vertical mounting orientation• Mounting point:• At least 1 m below the highest point on the structure• For tower installations, at least 3 m below the top ofthe tower• Ground wires – min. 10 AWG (5 mm2) and max. length:1 m. As a safety precaution, ground the airFiber X radioto grounded masts, poles, towers, or grounding bars.WARNING: Failure to properly ground yourairFiber X radio will void your warranty.• (Recommended) 2 Outdoor Gigabit PoE surge protectorsNote: For guidelines about grounding andlightning protection, follow your local electricalregulatory codes.• (Optional) For MIMO mode operation: A secondDuplexer of the same type as the one included with theAF‑11FX radio:• High-Band Duplexer (model AF‑11FX‑DUP‑H) or• Low-Band Duplexer (model AF‑11FX‑DUP‑L)• (Optional) If not using PoE: DC power source and12/30 AWG power cable.• Outdoor, shielded Category 6 (or above) cabling andshielded RJ‑45 connectors are required for all wiredEthernet connections.Installation OverviewWe recommend to configure your paired AF‑11FX radiosbefore site installation. The overview below summarizesthe installation procedure, and the subsequent sectionsprovide detailed installation information:• Install the Duplexer(s) in the AF‑11FX radio.• Connect the airFiber Gigabit PoE adapter to the DATAport, and connect your computer to the MGMT port.• Configure the AF‑11FX.• Install a ground wire and mount the AF‑11FX on theairFiber AF‑11G35 antenna (or a compatible antenna).• At the installation site, install the antenna with themounted AF‑11FX radio (see the antenna’s Quick StartGuide for installation instructions).• Connect the DATA port to your LAN, and connect power(PoE or DC power) to the AF‑11FX.• Establish and optimize the RF link..Installing the Duplexer for SISOMode1. Loosen the Captive Screw on top of the Duplexer Shroudand remove the Duplexer Shroud.DustCoversDuplexerShroud2. Remove the Dust Covers from the TX 0 and RX 0 ports ofthe AF‑11FX radio. Do not remove the Dust Covers fromthe RX 1 and TX 1 ports.3. Seat the SMA Ports of the Duplexer onto the TX 0 andRX 0 ports of the AF‑11FX, while positioning the LowChannel and High Channel ports to yield the requiredtransmit and receive frequencies.4. Secure the Duplexer to the radio by tightening thecollars on the SMA Ports.WARNING: Tighten the collars alternately, turningone collar a half turn, then the other a half turn,and so on, until both are fully tightened. Failure todo so may result in damage to the Duplexer.
