User Manual Dual C or Quad Ku Band TVRO Antenna (9497B-21)

Installation9497B-21 C/Ku-Band TVRO4.2. Site SurveyThe radome assembly should be installed at a location aboard ship where:1. The antenna has a clear line-of-sight to as much of the sky (horizon to zenith at all bearings) as is practical.2. Direct radiation into the antenna from ships radar, especially high power surveillance radar arrays, isminimized. The radome should be as far away from the ships Radar as possible and should NOT be mountedon the same plane as the ships Radar (so that it is not directly in the Radar beam path).3. The radome should be as far away from the ships high power short wave (MF & HF) transmitting antennas aspossible.4. The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned as close toone another as possible. This is necessary to reduce the losses associated with long cable runs.5. The mounting location is rigid enough that it will not flex, or sway, in ships motion or vibration. If theradome is to be mounted on a raised pedestal, it MUST have adequate gussets, or be well guyed, to preventflexing or swaying in ships motion.If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between thevarious considerations.4.3. Preparing For The Installation4.3.1. Unpack Shipping CratesExercise caution when unpacking the equipment.4.3.2. Inspect / InventoryCarefully inspect the radome panel surfaces for evidence of shipping damage. Inspect the pedestal assemblyand reflector for signs of shipping damage.4.3.3. Prepare ADE Mounting LocationPrepare the mounting location for the Radome. If the radome is to be bolted to the deck (or a platform)assure that the mounting holes have been drilled. Assure that the mounting hardware has obtained and isreadily available.4.3.4. Preparing BDE LocationPrepare the mounting location for the Below Decks Equipment. These equipments would normally beinstalled in a standard 19” equipment rack. Refer to the Antenna Control Unit manual for installation of theACU and the Terminal Mounting Strip.Refer to the vendor supplied manuals for installation of the other below decks equipments.Prepare other locations throughout ship for any other equipment which is not co-located with the ACU.4.3.5. Installing The System CablesInstall appropriate cables from Below Decks Equipment to the ADE Location(s).The cables must be routed from the above-decks equipment group through the deck and through variousship spaces to the vicinity of the below-decks equipment group. When pulling the cables in place, avoid theuse of excessive force. Exercise caution during the cable installation to assure that the cables are notseverely bent (proper bend radius), kinked or twisted and that connectors are not damaged.Assure that the cables have been run through watertight fittings and/or will not permit water entry into theship when the installation is completed. After cables have been routed and adjusted for correct cable lengthat each end, seal the deck penetration glands and tie the cables securely in place.4.4. Assembling the ADEThe assembly procedure described below begins by sub-assembling sections of the baseframe, radome and pedestal.Then these are assembled to form the ADE.4.4.1. 144” Radome, Baseframe and Antenna Pedestal System AssemblyRefer to the System Block diagram, General Assembly, Radome Assembly and Baseframe Assembly drawingsfor your system.4-2
