The installation, operation, and maintenance of the 5.6m Earth Station Antenna require qualified and experienced personnel. Kratos installation, operation, and maintenance instructions are illustrated for such personnel. Additionally, the antenna should be inspected by qualified personnel to verify proper installation, maintenance, and condition of equipment as described in Preventive Maintenance.

Kratos supplies all appropriate hardware/parts required for installation of the 5.6m ESA. All tools needed for the installation process, however, should be provided by the installation crew. Kratos recommends the following tools, as shown in Table 1.1, be used for a proper installation of the 5.6m. Table 1.1: Recommended Tools...

1.2 A-325 Tensioning Procedure Throughout the installation instructions set forth in this manual, there will be references to the A-325 hardware tensioning procedure. A-325 hardware must be properly tensioned to avoid slippage between bolted surfaces under high loads. Slippage can cause the corresponding assembly to move or slip, resulting in antenna misalignment.

Before beginning the installation process on the ground mount assembly, ensure that the foundation has been prepared. Foundation specifications are provided by Kratos and may be used as a reference by civil engineering personnel when preparing the foundation for local soil conditions. These specifications are available before the shipment arrives by contacting the Customer Service Center or your Account Manager.

Refer to the drawings, instructions, and schematics for the specific system being installed, per the information provided in Table 1.2. 2.1 Assembly Sequence & Helpful Tips Kratos recommends following these helpful tips regarding the sequence of assembly: Always use the correct provided hardware and use the appropriate sequence for tightening/torque, as per •...

2.2 General Subreflector Alignment Guidelines The primary goal of Subreflector alignment is for the Subreflector to be properly centered and for the height to be adjusted to the correct focal length for the antenna. Keep the following guidelines in mind during Subreflector alignment: A tape measure is generally used in order to center the Subreflector •...

These procedures provide details on how to correctly position the antenna on a desired satellite. NOTE: If intending to use a Kratos NGC Indoor Unit (NGC-IDU) or NGC Outdoor Unit (NGC-ODU) in order to control antenna, it is best to refer to the appropriate manuals of the NGC Documentation Package received with that unit.

Step 2 of 9: With the antenna positioned in Azimuth, with the transponder signal maximized, follow the same procedure as in Step 1, only this time using the Elevation direction (scanning up-and-down). Once again, do this until the transponder signal has been maximized. Step 3 of 9: Repeat this procedure, alternating between the Azimuth and Elevation excursions of the antenna, until you have peaked the antenna transponder amplitude.
Page 16
NOTE: it is more accurate and visually simple to minimize alternate set of transponder signals rather than maximizing the transponder of interest. Figure 3-4: Polarization at 45 Degrees from Optimum Setting Step 9 of 9: With all 24 transponder signals of approximately equal amplitude appearing on the Spectrum Analyzer screen, determine the specific antenna system and satellite parameters.

3.2 Subreflector Adjustment After the satellite has been acquired and testing has taken place with the Spectrum Analyzer, the subreflector may need to be adjusted to maximize optimum performance of your antenna. The following procedures should be followed if a subreflector adjustment is required to maximize optimum performance. NOTE: All INTELSAT Type Approved antennas do not require subreflector adjustment.

4.0 Preventive Maintenance These sections contain periodic preventative maintenance instructions for the 5.6m Earth Station Antenna. Included are instructions for performing inspections, preventative maintenance procedures, and cleaning. NOTE: Refer to applicable vendor manuals for any repair procedures that are not included in this manual. These sections describe cleaning, inspections, and preventative maintenance procedures.
Page 19
In the absence of any special inspection requirements, operational tests are the most effective means in isolating parts and assemblies requiring further inspection. During inspection, any noted damage and/or problematic condition which could preclude the continuation of proper operation (prior to the next scheduled inspection) should be recorded.

• IF APPLICABLE, check that drain holes in bottom of the enclosure and pedestal are not obstructed, and there is no evidence of water accumulation. Check enclosure doors for proper closure. Verify door seals are intact and free of tears, abrasions, and/or other damage. Check that all other seals are intact, and repair with coating of RTV-108 silicone rubber sealant as needed to seal exposed electrical fittings, bolt holes, and/or any other points of possible water entry to electrical components to maintain a waterproof condition.

4.3.2 Preservation of Galvanized Surfaces Remove all loose paint and corrosion by scraping, wire brushing, or using steel wool. Edges of existing paint can be blended with the metal surface using fine grit sandpaper. Wipe the surface to be painted with a soft rag dampened with a small amount of acetone, or equal.

4. Are there any particular precautions that can be taken to avoid damaging the feed window? All Kratos ESA feed windows are rated at .5 psi. This means placing any pressure on the feed window of more than .5 psi is likely to cause permanent damage to feed window, which will require replacement.
