Replacing the Antenna Position Sensor Board

Removing the Antenna Position Sensor Board

The antenna position sensor board is mounted with two screws that also secure the circulator and the LNC to the rotary joint.

  1. Disconnect the data cable from the antenna position sensor board.
  2. Using a 3 mm hex wrench, remove the two screws that hold the antenna position sensor bracket in place.
  3. Tilt the antenna position sensor board down slightly as you remove it, to make sure the sensor clears the encoder ring on the underside of the housing gear.

  2. Install the top two screws through the antenna position sensor board bracket, the plate on the right side of the LNC and the circulator, into the rotary joint.
  3. Connect the antenna position sensor board data cable to the port on the antenna position sensor board.
