SRT X-BAND RADAR SYSTEMS ANNEX 4.1.6 Grounding The grounding point is designed to provide electrical contact between the outer conductor of the elliptical waveguide and the ship’s ground. The waveguide should be grounded along the vertical run near the Antenna Group. A section of the cable jacket is removed and the ground strap tightly fastened to the outer conductor. The connection is then wrapped in butyl rubber tape and vinyl tape for protection from weather.
SRT X-BAND RADAR SYSTEMS ANNEX Figure 2: Figure 3: STEP 4 - Turn gasket inside out and place over end of waveguide. Apply very thin of coating silicone grease to gasket threads, the flip gasket over and against compression ring. Apply thin coating of silicone grease to outside surface of gasket. Refer to Figure 3. Clean any silicone grease from exposed copper using solvent. STEP 5 - Slip recessed side of flare ring over gasket. Alignment pin holes in flare ring and compression ring must be in line.
SRT X-BAND RADAR SYSTEMS ANNEX Figure 4: STEP 7 - Flatten tabs against flare ring. Use mallet as shown figure 5. Use only enough force to flatten tabs. Do not strike tabs so hard as to reduce thickness of metal. Trim any tab that protrudes past outside of groove in flare ring. After tabs are flattened and trimmed, tabs should be cleaned with solvent to remove any silicone grease.
SRT X-BAND RADAR SYSTEMS ANNEX Figure 6: STEP 10 - Waveguide should be check for leaks whenever connectors are attached, when connector-attached waveguide is received at site, or after installation. At dependable method is to apply soap solution to cable connector and pneumatic fittings. When mating two UG type flanges with the gasket grooves, two flange gasket must be used, if flange with gasket groove is mated to flange without groove, use one flange gasket.
SRT X-BAND RADAR SYSTEMS ANNEX STEP 3 - Apply silicone grease to the hole and slit of the rubber boot. Place the boot on the waveguide or cable and over the entrance hole. Mark the locations of the mounting holes. STEP 4 - Remove the boot and drill the mounting holes 5/16" (8 mm) through the wall or roof. For concrete, either drill holes through the material or drill larger holes deep enough to insert bolt anchors. STEP 5 - Place the boot around the waveguide or cable and over the entrance hole.

SRT X-BAND RADAR SYSTEMS ANNEX 4.4 Pressurisation After all connections have been completed, pressurise waveguide. Changes in temperature can cause moisture from outside air that enters waveguide to condense and seriously impair efficiency, so waveguide must be under pressure at all times. If moist air has entered, must be purged. Remove gas port plug located on connector at Antenna Group end of waveguide, and purge waveguide continuously until it is dry.
