3.3 Rough Outboard Alignment:

Adjust theodolite elevation angle to the ‘EL1’ value indicated in Figure 19. Point and focus the scope of the theodolite to target EL1 (do not move elevation) located on the rib #1, which is to the right of the top panel (top center of antenna with Andrew `Flash’ logo). While still focusing to the target, have the outboard cambolt slowly rotated until the upper edge of the target screw is within +/-15 seconds (0.0042 deg.) of the theodo- lite crosshair.

Do not tighten any hardware at this time.

3.3.1Repeat the procedure described in 3.3 for all 16 outboard target screws at loca- tion EL1.

3.3.2Travel around the reflector 2 or 3 times repeating all 16 adjustments, or until all 16 targets remain on EL1 within +/-15 seconds. Some target screws may not reach EL1, or may move while other ones are being adjusted. Repeating the adjustment around the reflector 2 or 3 times should solve this.

3.4 Rough Inboard Alignment:

Adjust theodolite elevation angle to the ‘EL2’ value indicated in Figure 19. Point and focus the scope of the theodolite to target EL2 (do not move elevation) located on the rib #1. While still focusing to the target, have the inboard cambolt slowly rotated until the upper edge of the target screw is within +/-15 seconds (0.0042 deg.) of the theodo- lite crosshair.

Do not tighten any hardware at this time.

3.4.1Repeat the procedure described in 3.4 for all 16 inboard target screws at location

EL2.

3.4.2Travel around the reflector 2 or 3 times repeating all 16 adjustments, or until all 16 targets remain on EL1 within +/-15 seconds. Some target screws may not reach EL, or may move while other ones are being adjusted. Repeating the adjustment around the reflector 2 or 3 times should solve this.

3.5 Fine Outboard Alignment:

NOTE:

Tightening of seam hardware near the outer rim during `Fine Outbard Alignment’ must be done from a ladder outside the reflector. Do not put any weight or excert any force on the reflector while tightening the outer seam hardware.

Again, adjust theodolite elevation angle to the EL1 value. Point and focus the theodolite again to target EL1 located on rib #1. While still focusing to the target, have the out- board cambolt slowly rotated until the upper edge of the target screw is again within +/- 15 sec. (0.0042 deg.) of the theodolite crosshair.

After each individual adjustment, semi-tighten (compressed lockwasher) seam hard- ware #26 and #27 (3rd and 2nd from the rim) on the rib being adjusted.

3.5.1Repeat the procedure described in 3.5 for all 16 outboard target screws at loca- tion EL1.

3.5.2Repeat all 16 adjustments again. This time, after each individual adjustment, fully tighten the cambolt nut, as well as seam hardware #26, 27 and 28 (#28 is the outer- most on the seam) on the rib being adjusted.
