Securing the Radar antenna to the pedestal

MountingAntennaAntennaMounting

Before securing the Radar antenna to the pedestal, ensure that:

  • The pedestal base is securely fixed to the platform.

  • The cable is NOT attached.

  • The pedestal power switch is in the OFF position.

  • The pedestal unit has a cap fitted over the open array mounting shaft to protect the protruding co-axial pin. This cap must remain in place until you’re ready to fit the antenna to the pedestal unit.

Important

You MUST ensure that the antenna does not come into contact with the delicate protruding co-axial pin. This is a critical component and should be treated with caution. Follow all the instructions provided below, and ensure that the alignment guides are used.

  1. Fit the 4 threaded alignment guides to the studs on the underside of the antenna. Ensure a close fit. The alignment guides are essential to help prevent damage to the coaxial pin.
  2. Remove the protective cap from the antenna shaft. Retain the cap for future use.
  3. Position the antenna mounting bracket on the Port to Starboard axis of the pedestal.
  4. Lift the antenna into position, ensuring it is in the correct orientation and that the threaded alignment guides are fitted. Carefully align and slowly lower the antenna.
  5. Once the antenna is in position, remove the alignment guides.
  6. Grease the 4 securing studs with the supplied Denso paste.
  7. Use the 4 nuts and associated washers to secure the antenna to the pedestal, as shown in the following diagram. Tighten each nut to 10 Nm (7.4 lb ft) torque.
