Step 38. Refer to Table 4-1 for parts list and Figures 4-1, 4-2 and 4-3 for assembly drawing.
Step 5. Insert one Gasket (item 101) into the grooved flange of the ODU output flange.
Attach feed assembly (horn and OMT) to the output flange of the BUC as
shown in Figure 4-1, using quantity eight each 10-32x5/8 screws (item 102)
#10 lock washers (item 103). Loosely assemble all screws and washers then
tighten securely.
Step 6. Attach the Transmit Reject Filter and LNB to the receive port of the OMT as shown
in Figure 4-1.
Step 16. Attach the BUC Tail Mount Bracket (item 2) to the mounting plate (item 1) using
hardware (items 6, 7 & 14) as shown in Figure 4-2. Tighten screws securely.
Step 17. Assemble Mounting Plate (item 1) to the Boom Arm with the Feed Support Bracket
(both supplied with antenna) using hardware (items 4, 6, 7 & 8) as shown in Figure
4-1.
Step 18. Install Bracket Assembly (item 201) and Mounting Plate (item 203) to the Boom
Arm using Hardware (items 204, 206, 207, 208) as shown in Section A-A, Figure
4-1. Do not tighten hardware at this stage.
Step 19. Attach the support brace (item 202) to the mounting plate (item 1) as shown in
Figure 4-2. Please note, some kits may require additional support brackets, (item
15), to attach the support brace to the mounting plate, see Figure 4-3.
Step 20. Attach the bottom of the Support Brace (item 202) to the Boom Arm using the
mounting assembly installed in Step 5 as shown in Section A-A, Figure 4-1.
Loosely assemble all screws, nuts and washers then tighten securely.
Step 21. Place feed assembly and BUC on the mounting plate. The “neck” of the horn should
sit in the cradle of the horn support. Attach the BUC to the rear support plate using
one each 3/8-16 bolt (item 104), 3/8 lock washer (item 105) and 3/8 flat washer
(item 106). Do not tighten completely.
Step 22. Secure horn with top strap and 1/4-20 bolts and lock washers (provided with
antenna system). Finger-tighten bolts.
Step 23. Adjust the feed / BUC / LNB assembly to set the desired polarization. Tighten the
horn strap and BUC rear mount bolt securely. The RF head assembly is complete.
Refer to antenna system and VSAT system operation manuals for antenna alignment
and system operation.
Step 39. Radyne ComStream does not provide the OMT assembly. Radyne ComStream can provide the
transmit reject filter as an option.
