BWA - BTR Microwave Transceiver and RPE Installation / 27 October 12, 1999 Method 08-02834.7 Alignment of BTR’s Using the Alignment ToolThe alignment of an LMDS system is accomplished by aligning the BTR within a sector to an azimuth and elevation that defines RF coverage of that sector.This alignment procedure can be done using either BTR mount.Note: In the event this is an initial installation and there are no CPE (CTR’s mounted) location. A technician will need to go 2 or more engineered CPE locations. Once there the technician will need to validate that there is an antenna mast to mount the CTR to. Then Figure 17 - Vertical Fine Adjustment Tool Mounted to the Antenna Mast/Dual Mount31 Loosen the bolts on the back of the BTR’s so that the Vertical Alignment can be done. In order to adjust the vertical tilt up or down turn the turn-buckle in order to do so.32 The dual mount antenna assembly will now need to be aligned.33 End of Procedure.Procedure 3 - Install the BTR(s) Using the Dual MountStep Action Observation
28 / BWA - BTR Microwave Transceiver and RPE Installation Method 08-0283 October 12, 1999the technician will need to place a white paper plate or balloon on that mast in order to align the BTR for that sector.Procedure 4 - Alignment of BTR’s Using the Alignment ToolStep Action Observation1The alignment tool must first be put together. Steps 2 through 9 cover the installation of the alignment tool.2Attach the long threaded rod (H) into the side of the top bracket (A). The top bracket is the plate with the counter-sunk screw holes in the top. (Figure 15 & 16)3Hold the top bracket so that the threaded rod is facing to the right and the counter sunk holes are up. Attach the right side bracket (C) to the top bracket using (2) 6/32 X 5/8 allen head screws making sure the screws are flush with the top bracket when installed. The right side bracket should have the slots and the cut-down portion of the brackets facing away from you when it is installed onto the top bracket. You will also notice there is a straight mark engraved on the outside of the right bracket. (Figure 15 & 16)4Hold the top bracket so that the threaded rod is facing to the right. Attach the left side bracket (B) to the top bracket using (2) 6/32 X 5/8 allen head screws. The left side bracket should have the slots and the cut-down portion of the brackets facing away from you when it is installed onto the top bracket. There is no straight mark engraved on the outside of the left bracket. (Fig-ure 15 & 16)5Attach the tilt protractor (E) to the tilt/azimuth bar (F) with (2) 8/32 flat head screws. Hold the tilt/azimuth bar in your right hand so the engraved straight line is up and to your left. Place the tilt protractor (E) in your left hand so the number slots are facing towards the right. Using the flat head screws secure the tile protractor to the end of the tilt/azimuth bar (F). (Figure 15 & 16)
BWA - BTR Microwave Transceiver and RPE Installation / 29 October 12, 1999 Method 08-02836Slide the tilt/azimuth bar (F) on to the threaded rod so that the tilt protractor is sets flush against the right bracket (C). Secure the tilt/azimuth bar (F) with a wingnut and washer so that the 0 on the tilt protractor (E) is lined up the the engraved mark on the right bracket (C). (Figure 15 & 16)7Attach the azimuth protractor/scope platform (D) to the tilt/azimuth bar (F) with the protractor pointed to the engraved straight line on the tilt/azimuth bar (F). Secure the azimuth protractor/scope platform using the short 1/4-20 thumb-screw, wingnut and washer. (Figure 14 & 15)8The bottom support bracket (J) will now need to be attached to the right and left side brackets. Turn the alignment tool upside down, using the (2) small screws secure the support bracket on the bottom of the right and left side brackets.9Set the BTR attachment bracket so that it is to the left and the azimuth protractor/scope platform to the right. Attach the riflescope on the scope mounts with the eyepiece towards you.10 Screw the long 1/4-20 thumbscrew into the threaded hole on the top bracket (A). (Figure 14 & 15)The alignment tool is now installed and ready to be used to align the BTR’s.11 At the roof location the alignment tool mounts to the back of the BTR. 12 Slide the alignment tool over the heat sink so that it fits flush, then tighten the long thumbscrew so that is secures the alignment tool to the BTR.13 Infomation Note: Azimuth and tilt of the BTR is set by using the relative position of one or more CPE’s (two are suggested, since two units would not have common errors if we have bad survey data) to the BTR. 14 Loosen the BTR’s tilt and azimuth adjustment so that it can be adjusted for tilt and azimuth set-tings.15 Using the Engineering package look at the offset data sheet for the first CPE. Preset the azimuth and tilt offset for that CPE (pay attention to the sign of the offset).Procedure 4 - Alignment of BTR’s Using the Alignment Tool (Cont’d)Step Action Observation
30 / BWA - BTR Microwave Transceiver and RPE Installation Method 08-0283 October 12, 199916 Adjust the BTR until the selected CPE is in the center of the crosshairs of the scope.17 Tighten the BTR tilt and azimuth adjustment clamps.18 Verify that the CPE is still in the crosshairs. If it is not redo steps 16 and 17.19 Loosen the azimuth and tilt adjustment on the alignment tool and rotate the scope to the center of the second selected CPE in the scope crosshairs.20 Tighten the tilt and azimuth adjustment bolts on the alignment tool.21 Read the azimuth and tile offset to the second CPE. If the measured tilt and azimuth offset is the same as predicted (+/- 0.5 degree) for both CPE’s the setting of the BTR is considered GOOD.Note: If they are not, then one or the other (or both) of the CPE’s have bad survey data (either lat/long or building height or both). To determine the CPE with the bad data, select a third CPE and follow steps 19 thru 21. The two CPE’s that agree must be considered as correct, since the odds of having a common data error at two different CPE’s are very small. At this point, the CPE with bad data should have its tilt and azimuth offsets measured (steps 19 thru 21) and the results recorded on the offset data sheet and advise the RF Engineer of this. If two of the three selected CPE’s do not agree with predicted offset from the BTR, then the RF Engineer should be contacted for a solution. Those CPE with measured offsets that are different from the expected offsets must be highlighted for link budget corrections for the tilt and azimuth offsets.Procedure 4 - Alignment of BTR’s Using the Alignment Tool (Cont’d)Step Action Observation
BWA - BTR Microwave Transceiver and RPE Installation / 31 October 12, 1999 Method 08-0283Figure 18 - Alignment Tool Parts22 Note: The alignment tool can also determine the initial setting of the BTR tilt or it can check an existing tilt setting of the BTR. To initially set the BTR tilt, preset the desired tilt angle using the offset protractor and adjust the BTR so that the scope platform is level. The BTR is now tilted (up or down) the required amount. To check an existing tilt, move the scope platform unitl it is level. Read the existing tilt from the tilt protractor.23 Repeat this procedure as necessary for all BTR’s.24 End of Procedure.Procedure 4 - Alignment of BTR’s Using the Alignment Tool (Cont’d)Step Action Observation (H)(A)(B)(C) (F) (D)(E)(G)(J)
