WAVEGUIDES INSTALLATION. (CONT)
1.
Locate flexible waveguide PN 102824 (1) on shipping pad.
2.
Remove four screws securing waveguide cover (2) to flexible waveguide (1).
Retain hardware for use in
repacking.
3.
Insert preformed packings (3 and 4) into recesses in waveguide adapter (5). Using four screws (6) and
lockwashers (7), attach flexible waveguide (1) and waveguide adapter (5), along with wire rope assembly (8) to
azimuth horn and polarizer (9).
4.
Insert dehydrator cartridge (10) into dehydrator cartridge adapter (11).
Install this assembly Into bottom of
waveguide adapter.
CAUTION
When performing step 5, position flexible waveguide so that curved portion will clear elevation antenna
drive when azimuth antenna rotates.
5.
Insert preformed packing (12) into recess in flange on free end of flexible waveguide (1). Install flexible
waveguide on azimuth antenna yoke waveguide flange (13) and, using waveguide coupling (14), secure.
6.
Locate flexible waveguide PN 174600-1 (15), rigid waveguide assembly PN 140771-1 (16), and directional
coupler PN 174601-1 (17) on shipping pads.
7.
Attach flexible waveguide (15) to rigid waveguide assembly (16) by placing preformed packing (18) into recess in
flange and securing with four screws (19), lockwashers (20), and flat
8.
Insert preformed packings (22 and 23) into recesses in flanges of waveguide adapter (24). Using four screws
(25), lockwashers (26), and flat washers (27), secure adapter between flexible waveguide (15) and directional
coupler (17).
9.
Insert dehydrator cartridge (28) into dehydrator cartridge adapter (29).
