To install the waveguide switch:
1. Install the appropriate O-ring between the weldment and port 1 of the waveguide
switch.
a. If both components have O-ring grooves, use Comtech EF Data Part #
32P1039.
b. If only one component has an O-ring groove, use Comtech EF Data Part #
32P1037.
2. Using four 6-32 x 1/2” socket head cap screws, #6 split lockwashers, and #6 flat
washers, attach the weldment to port 1 of the waveguide switch. Tighten the cap
screws firmly.
3. Install the appropriate O-ring between the antenna and the weldment.
4. Using four 6-32 x 7/8” socket head cap screws, eight #6 flat washers, four #6
split lockwashers, and four 6-32 nuts, attach the weldment to the antenna.
Tighten the cap screws firmly.
5. Install the appropriate O-ring between port 3 of the waveguide switch and the
termination.
6. Using four 6-32 x 1/2” socket head cap screws, #6 split lockwashers, and #6 flat
washers, attach the termination to port 3 of the waveguide switch. Tighten the
cap screws firmly.
7. Install the appropriate O-ring between port 2 of the waveguide switch and a
section of the flexible waveguide.
8. Using four 6-32 x 1/2” socket head cap screws, #6 split lockwashers, and #6 flat
washers, attach the flexible waveguide to port 2 of the waveguide switch. Tighten
the cap screws firmly.
9. Install the appropriate O-ring between port 4 of the waveguide switch and the
second flexible waveguide.
10. Using four 6-32 x 1/2” socket head cap screws, #6 split lockwashers, and #6 flat
washers, attach the flexible waveguide to port 4 of the waveguide switch. Tighten
the cap screws firmly.
11. Install the appropriate O-ring between the flexible waveguide attached to port 2
of the waveguide switch and the waveguide flange on the RFT “A.”
12. Using four 6-32 x 7/8” socket head cap screws, four #6 split lockwashers, eight
#6 flat washers, and four 6-32 nuts, attach the flexible waveguide (attached to
port 2 of the waveguide switch) to the waveguide flange on the RFT “A.”
Tighten the cap screws firmly.
