General Requirements | 3-19
To apply the anti-seize lubricant,
1. Wear appropriate person protection equipment to avoid contact with skin and eyes.
This includes safety glasses, neoprene or nitrile gloves, and clothing sufficient to
limit skin exposure.
2. Ensure that mating surfaces (screw holes) are clean, dry and free of dirt, debris, or
loose surface rust.
3. Use a brush or lint-free cloth to apply a think coat of anti-seize to the screws and
bolts that require protection, as shown in Figure 3.8. The anti-seize should be
applied right down to the base of the threads.

Applying the Anti-Seize Lubricant
4. Spread the lubricant to a thin film without any lumps.
5. Reassemble the parts using normal torque values.
6. Wipe off any excess material with a disposable towel.
Waveguide Connections
If necessary, connect a section of flexible waveguide between the orthogonal mode
transducer (OMT) transmit port and the IBUC Tx RF output (or optional Rx reject
filter). The waveguide should be attached to the antenna feed according to the
manufacturer’s instructions. Use proper gasketing methods to prevent water entry and
subsequent damage.
Note:
During installation, be sure to remove the sticker shown in Figure 3.9 that covers the
waveguide flange. The sticker itself does not create a pressure window and will allow
moisture to enter the waveguide. Also be sure to install the waveguide gasket into the
channel identified in Figure 3.9 to ensure a good seal between surfaces. Do not re-use
old gaskets.
