1027144–0001 Draft – Revision D.01 4–6 Installing IFL cables RT installationDetailed instructions for installing the IFL and lightning arrestorare included in the following sections.Determine the IFL cable route, from ODU to IDU. Consider theguidelines below. Every building and rooftop is unique; for thisreason, some of these guidelines may not apply to yourinstallation:•The most important considerations are the ODU and IDUlocations and the building entry point. The entry pointshould be as close as possible to the ODU. Refer to the RTrooftop drawings. (See also page 5–3.)•The maximum IFL cable length is 1000 feet (305 meters).•Where possible, use existing conduit.•You must use a pull box to facilitate pulling cables throughconduits if routing cable through bends totaling more than360°.•If existing conduits can not be used and the cable will beexposed, refer to building codes to determine proper cableinsulation type. For example, plenum rated cable must beused if cable will be run above suspended ceilings.•If you are installing the IFL cable(s) inside a conduitthat contains power cables, you must use plenum–ratedcable.•Look for cable routes that will be easily accessible, such asstacked telco closets etc.•Older buildings may not have stacked telco closets. Youmay have to route the cable back and forth, from one side ofthe building to the other.•Never run the IFL cable across corrugated roofing.

Position the mast interface and permanent mast clamp onopposite sides of the mast, with the interface on the sameside as the temporary collar, as shown in figure 6-9.Allow the bottom surface of the mast interface to rest on thetop surface of the temporary installation collar.Figure 6-9 Installing the antenna mounthb068MastPermanentmast clampMastinterfaceClamp nut(1 of 4)Swing clamptoward interface.Elevationadjustment armAlign the face of the mastinterface so that these twosurfaces are parallel.3. Swing the clamp toward the interface until you can“capture” the clamp by swiveling the free–swinging boltsinto the two slots in the clamp, as shown in figure 6-9.The elevation adjustment arm (shown in figure 6-9) must bebehind the antenna (not installed yet). This means it will beon the side of the interface that is farthest from the HT.In some cases, to point the antenna in the right direction, itis necessary to install the mount upside down, with theelevation adjustment arm at the top of the mast interface.This is acceptable, as long as the mount is installed so theelevation adjustment arm will be behind the antenna.4. Align the mast interface and temporary installation collar sothe rectangular face of the interface is parallel with the flatsurface of the collar, as shown in figure 6-9.5. Finger tighten the four mast clamp nuts so the mastinterface and permanent mast clamp are snug and withoutexcess movement.You should be able to smoothly pivot the mast interface andmast clamp around the mast to permit coarse azimuthadjustment.(You fully tighten the mast clamp nuts later, aftercompleting all adjustments.)

1027144–0001 Draft – Revision D.01 Installing ODUs 6–23RT installationGrounding the ODU requires several connections, as shown infigure 6-21. In making the ground connections, follow thesepractices:•For all ODU ground connections, use compressionconnectors (such as compression lugs or compressionclamps).•For all threaded ground connections, use a flat washer andlock washer (with the lock washer next to the nut).Ground the ODU as follows:1. Connect one end of the ground cable (No. 6 AWG orgreater, green) to the ODU ground connector, which isshown in figure 6-21.2. Connect the ground cable to a bolted joint on the mastmount.Important: For this connection, strip the cable but do notcut it. See figure 6-21. The cable continues from the boltedjoint to the ground point.3. Connect the ground cable to a suitable ground point on therooftop.The best ground point for the ODU is an earth–referencedroof ring conductor that follows the perimeter of thebuilding, constructed according to the requirements ofNFPA 780 or a similar regulatory code. However, such aconductor is not always present. Other alternatives areacceptable, as long as they comply with the groundingrequirements detailed in the Hub and Remote Terminal SitePreparation Guide.Building steel can also be used as a ground point. However,before using building steel, verify that the steel structureis electrically continuous throughout the entire buildingand that it is properly connected to earth ground. Fordetailed grounding requirements, see the Hub and RemoteTerminal Site Preparation Guide.4. Apply anti–oxidant (HNS 9008224–0002) to each groundlug (points 1, 2, and 3 in figure 6-21).5. Apply 1/2–inch (13–millimeter) heat shrink tubing (HNS9007488–0005) to each ground lug after the connection iscomplete.Important: You must slip the heat shrink onto the cablebefore you make the connections.Note: A resistance of less than 5 ohms is desirable from theODU to earth, including the earth field.6.12Grounding the ODU
