22 / BWA - BTR and RPE Installation Method 08-0283 August 11, 20004.8 Alignment of BTR(s)The line of sight alignment of the outdoor units is accomplished by aligning the BTR(s) to an azimuth and elevation that define RF coverage of that sector. The azimuth and elevation are located in the Engineering Package.This alignment procedure can be done using either single or dual BTR mount configuration.The following steps identify the procedure for aligning the BTR(s) to the proper azimuth that is stated in the Engineering Package. The fundamental aspect of this procedure is to align the BTR(s) using fixed reference points (i.e. CPE(s) or Landmarks) and their associated azimuth offset from the required pointing azimuth of the BTR(s). The required elevation/tilt angle will be set using an inclinometer.Procedure 6 – Alignment of BTR(s) (Page 1 of 4)Step Action Observation1The alignment tool must first be put together. Steps 2 through 10 cover the assembly 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. Refer to Figure 12 & 13.3Hold 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 two 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.Refer to Figure 12 & 13.4Hold the top bracket so that the threaded rod is facing to the right. Attach the left side bracket (B) to the top bracket using two 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. Refer to Figure 12 & 13.
BWA - BTR and RPE Installation / 23 August 11, 2000 Method 08-02835Attach the tilt protractor (E) to the tilt/azimuth bar (F) with two 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). Refer to Figure 12 & 13.6Slide the tilt/azimuth bar (F) onto the threaded rod so that the tilt protractor is set 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 with the engraved mark on the right bracket (C).Refer to Figure 12 & 13.7Attach 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 thumbscrew, wingnut and washer. Refer to Figure 12 & 13.8The 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 two 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). The alignment tool is now installed and ready to be used to align the BTR(s).Refer to Figure 12 & 13.11 Loosen the BTR(s) tilt and azimuth adjustment so that it can be adjusted for tilt and azimuth settings.Procedure 6 – Alignment of BTR(s) (Page 2 of 4)Step Action Observation
24 / BWA - BTR and RPE Installation Method 08-0283 August 11, 200012 Locate the "BTR Antenna Alignment Using Landmark" sheet within the Engineering Package. Preset the azimuth offset from 0 degrees on the alignment tool by rotating the scope plate to the left (if the azimuth offset is negative) or to the right (if the azimuth offset is positive) by the offset amount for the landmark that is being used. Azimuth is set.Note: Each increment on the azimuth plate is 1 degree.Note: Azimuth and tilt of the BTR is set by using the relative position of one or more landmarks (two are suggested, since two landmarks would not have common errors to the BTR).Refer to Figure 14.13 At the roof location, the alignment tool mounts to the back of the BTR. 14 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.Refer to Figure 15.15 Adjust the BTR until the landmark point is in the center of the crosshairs of the scope.16 Now the Tilt will need to be set.Note: The inclinometer has two scales on the device. The one on the left shows actual degrees, and the one on the right shows a percentage used in calculating distance to target. USE THE SCALE ON THE LEFT FOR BTR ALIGNMENT.Note: The proper BTR Tilt can be found in the Engineering Package.17 Place the inclinometer on the heat sink fins on the back of the BTR.Take a reading with the inclinometer using the proper scale.Note: Do not place your eye up against the inclinometer. Look at the reading from 4 to 8 inches away from the inclinometers viewing window.Note: Line up the RED center indicator with the BLACK angle identifier in the viewing window of the inclinometer.18 Adjust the BTR as needed and snug the bolts on the BTR tilt adjustment clamps.19 Recheck the tilt, repeating steps 17 and 18.20 Tighten the BTR tilt and azimuth adjustment clamps.Procedure 6 – Alignment of BTR(s) (Page 3 of 4)Step Action Observation
BWA - BTR and RPE Installation / 25 August 11, 2000 Method 08-028321 Verify the landmark is still in the crosshairs. If it is not, redo steps 15 and 20.22 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.23 Tighten the tilt and azimuth adjustment bolts on the alignment tool.24 Read the azimuth offset from 0 degrees to the second landmark (if available). If the measured azimuth offset matches the Engineering Package value, the alignment is complete.Note: If they are not, then one or the other (or both) of the landmarks have bad survey data (either lat/long or building height or both). To determine the landmark with the bad data, select a third landmark and follow steps 15 thru 21. The two landmarks that agree must be considered as correct, since the odds of having a common data error at two different landmarks are very small. At this point, the landmark with bad data should have its tilt and azimuth offsets measured (steps 15 thru 21) and the results recorded on the offset data sheet and advise the RF Engineer of this. If two of the three selected landmarks do not agree with predicted offset from the BTR, then the RF Engineer should be contacted for a solution. The CPE with measured offsets that are different from the expected offsets must be highlighted for link budget corrections for the tilt and azimuth offsets.25 Repeat this procedure as necessary for all BTRs.26 End of Procedure.Procedure 6 – Alignment of BTR(s) (Page 4 of 4)Step Action Observation
