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) = 28.15 - ƒIF IN (GHz) RX: ƒIF OUT (GHz) = 28.15 - ƒRF IN (GHz) Note: Electrostatic deposition powder coat, scratch free.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°.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.
