Andrew ES76PK-1 installation instructions Installation Procedures, Install Brass Rod Holders

1.3 Install Brass Rod Holders:

Install brass rod holders in seam hole #11 on rib #2, 7, & 10 in Figures 19 and 20. Reflector seam screws must first be removed in these locations. Make sure the bottom of the rod holders are sitting flush on the reflector panels and they are pointed toward the theodolite assembly.

Attach the alignment stick to the rod holder in rib #2 with the knob assembly.

1.4 Install Target Screws:

Install target screws in all 16 ribs as shown in Figure 19 (reflector seam screws must first be removed in these locations). Be sure that target screws are fully seated on the rib surface, not the reflector surface. This is best done during assembly of Reflector/Backstructure.
