Converted Frequency Formula
Use the following formula to calculate the converted frequency:
TX: ƒRF OUT (GHz) = ƒIF IN (GHz) + 27.35
RX: ƒIF OUT (GHz) = ƒRF IN (GHz) - 27.35
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°.
