Foreword Purpose Proprietary Data The scope of this manual is to provide preventive maintenance information together with detailed operational procedures that are required to support maintenance of a 4.5Meter Transportable Receive/Transmit Earth Station Antenna. The manual is comprised of five distinct sections to provide convenient reference for authorized operator/service personnel requiring technical information on general system or specific subsystem equipment.
Section 1 - Introduction 1.3 The operating section includes detailed equipment operating procedures required during normal system operation, while the preventive maintenance section enables qualified personnel to maintain the equipment using standard hand tools. The drawing section provides installation, mechanical, electro-mechanical subsystem and subsystem component reference drawings as an aid for maintenance and operation.
3.0 Description that includes four outriggers for maximum stability. The trailer is provided with a 2-5/16” ball hitch as a standard. Optional hitch assemblies are available. Optional storage boxes are also available for mounting on the trailer assembly. 3.1 Primary Radiator. The primary radiator design consists of a variety of interchangeable feed systems for wide ranges of applications.

Section 2 - Operation 1.0 Normal System Set-Up Procedure Elevation Strut Clamp - must be loose prior to raising/lowering reflector WARNING: Extreme care must be taken during the following system set-up and stowing procedures to avoid bodily injury and/or equipment damage. 1.1 Choose a site which is as level as possible with the rear of trailer facing as closely as possible in the direction of the satellite.
Unlock safety pins from strut clamping knobs 1.8 Set antenna to desired elevation angle. Remove locking pin from handwheel on elevation jack shaft by pressing quick release button on head of locking pin. Remove handwheel and reinstall on azimuth jack shaft. Align corresponding holes and insert locking pin into handwheel assembly. Release azimuth brake by rotating brake handle counterclockwise and sweep in azimuth to locate signal. After desired satellite is found, peak EL and AZ for optimum signal.
Stowed Reflector & Feed Support Struts 3.0 Towing CAUTION: Ensure front trailer jack is contacting ground before raising outrigger jack assemblies. 3.1 When hooking trailer to the tow vehicle, position trailer tongue over ball hitch and carefully lower jack to engage hitch assembly. Ensure that the trailer jack is fully retracted and tilted into its tow position, prior to towing. 3.2 The safety chains should be crossed under the tongue and connected to the tow vehicle.
Section 3 - Periodic Preventive Maintenance 1.0 General 1.1 This section contains periodic preventive maintenance instructions for the 4.5-Meter Transportable Earth Station Antenna. Provided in this section are inspection and preventive maintenance procedures including cleaning, lubrication and painting procedures deemed within the capabilities of the average station technician.
A. Trailer 1. Check tire pressure, it should be maintained at 85 psi. 2. Lubricate the four corner jacks and the trailer jack. 3. Check ball on the towing vehicle to ensure it has not been damaged or worn. The brake system will not function properly unless the ball size is 2-5/16 inch diameter. 4. Check the fluid level in the brake system master cylinder and refill it as required to 1/2 inch below the top of the filler cap. Use only DOT 3 automotive brake fluid. 5.
A-325 Hardware Tensioning Procedure 1. Lubricate bolt threads with stick wax to reduce friction. Do not allow wax under flat washer. 2. After connections are completed, tighten bolts until surfaces are joined and nuts are snug. Do not proceed with Steps 3 and 4 below unless the connection is final. If bolts are loosened after Steps 3 and 4, discard and replace with new hardware. Repeat all steps. 3. Mark nuts and end of bolts with straight line. See Figure A. 4.
4.0 Lubrication 4.3 Motor Gearbox/Housing Fill and Drain Requirements 4.1 For long life and trouble-free operation, be certain not to extend the lubrication schedule beyond the frequency recommended in Table 2, Lubrication Chart. The frequency should be shortened if the antenna is subjected to extensive use or an adverse environment (e.g. high temperature, extended periods of rainfall, high humidity, dust storms, etc.).
4.6. Lubricant Characteristics B. Mobil SHC-624tm - A low temperature synthetic oil for worm gear reducers. Operating temperature range is -40° to + 200° F (-40° to +93° C). A. Mobil Temp SHC-32tm - A non-soap hydrocarbon fluid type grease. Operating temperature range is -65° to+ 350° F (-54° to +177°C). Type of Service C. Open Gear Lubricant - A non-flammable asphaltic type aerosol lubricant. “REALFILM - EVAPO-H OPEN GEAR SHIELD” or equivalent. Lube Type No.
Section 4 - Drawings 1. This section contains installation/drawings and wiring and schematic diagrams for the 4.5-Meter Transportable Receive/Transmit Earth Station Antenna System. 3. The wiring and schematic diagrams illustrate the interface between electromechanical subsystem components. 4. The drawings contained in this section include: 2. The installation drawings describe the subsystem assembly and the mechanical interface between system component assemblies and the vehicle.
