Reflector

 

 

Notice

Alignment

Temperature change during calibration or alignment of this reflector will adversely effect

 

the alignment quality, and therefore, the performance of this antenna. Calibration and

 

alignment should only be done during stable temperature conditions, typically after sun-

 

set or under heavy cloud cover.

 

Before the theodolite installation/calibration, or rerflector alignment, all panel seam hard-

 

ware should be loose including the lifting tab hardware. The only exception to this is the

 

torque tube support strut hardware and brackets, which should be tight. The subreflector

 

struts should not be attached to the reflector at this time.

Theodolite

During alignment, do not step on drum skin or directly on ribs. This will affect the

Installation

theodolite position.

Step 1

Cut two pieces of 2x4 lumber to length and lay on top of ribs at hub tab locations. Lay

plywood on top of 2x4 lumber. Refer to Figure 17.

 

Before installing the theodolite support kit onto the torque tube make sure to set the

 

height of the support/theodolite assembly as shown in Figure 18. This will help in the

 

subsequent adjustments.

 

Assemble theodolite support kit on top of torque tube as shown in Figures 18 and 19.
