Information is subject to change without notice. Nortel reserves the right to make changes in design or components as progress in engineering and manufacturing may warrant.© 2000 Northern Telecom Ltd.Converted Frequency FormulaUse the following formula to calculate the converted frequency: TX: ƒRF OUT (GHz) = 28.60 (GHz) + ƒIF INPUT (MHz) RX: ƒIF OUTPUT (MHz) = 28.60 (GHz) - ƒRF INPUT (GHz) Note: The antenna has an option of a hydrophobic coating that can help to reduce ice build-up effect.Note: Vent holes are covered with a GoretexTM patch.Note: The transceiver mounts to a vertical pole of 2.5” to 4.5” outside diame-ter. It has a range of motion of 90° over and -60° under horizon. The bases of the antenna mount can rotate ±180°.Note: The module connector is N-Type female. The receive IF input/output cables present a male N-Type connector. The Tx IF and the Rx IF test ports are SMA-Type female. The Telemetry port: 6 pin female military-style con-nector.Technical Assistance Contact InformationIn case additional technical assistance is required, or the transceiver unit is damaged upon receipt, contact Nortel Networks.Nortel Networks Broadband Wireless Access (BWA) provides 24-hour customer service and technical support to ensure your service operation is trouble-free.
