- INSTALLATION AND SERVICE REPORTS

(1) Fit the antenna mounting bracket on top of the swing casting by inserting the 8
supplied M10 x 40 mm button head allen key screws through the aligning holes,
and tightening the 8 supplied M10 barb nuts on the underside of the swing
casting. Apply Loctite to all screws.
(2) Remove the protective caps, tapes, etc. from the antenna and waveguide. Ensure
the waveguide faces are clean and free from grease.
(3) Carefully slide the antenna into the mounting bracket slot and align the four
mounting holes. Insert the 4 supplied M8 x 75 mm bolts, each fitted with an M8
washer, through the holes to hold the antenna in place. Loosely fit another washer
and 4 of the supplied M8 Nyloc nuts to each of the bolts. Apply Loctite to all
screws.
(4) Position the waveguide by fitting its support tab onto the M8 stud on the front
face of the mounting bracket, and ensuring the flanges at each end align with their
respective components.
(5) Secure the waveguide to the antenna input with the 4 supplied bolts, nuts and
washers, having fitted the round O-ring seal into the flange groove.
(6) Secure the waveguide to the rotating joint with the 4 supplied M4 x 12 mm cheese
slot pan head screws and M4 crinkle washers, having fitted the rectangular
O-ring seal into the flange groove.
(7) Fit the remaining M8 Nyloc nut and M8 washer to the M8 stud on the front face of
the mounting bracket to secure the support tab.
(8) Tighten the M8 bolts fitted through the antenna and mounting bracket to a torque
of 29 Nm.
(9) Waterproof the waveguide joint by sealing with a layer of greased plastic
compound such as Henleys compound or Denso-Tape.
