Feed Strut Assembly

Step 1

Step 2

Position white surface of center pad toward feed window and attach pad to center plate using supplied ¼ x 1-½ in. nylon screw, flatwashers and nuts. Install flatwashers under both screw head and corresponding nut as shown in Figure 64. Tighten mounting hard- ware allowing only slight compression (0.060” max.) of center pad material. Use remain- ing nylon nuts as locknuts and distort excess screw thread to prevent disassembly.

Loosely attach corresponding feed strut brackets (P/N 49694/49695) to concave side of reflector at points B, C, E, and F as shown in Figure 65.

Use A-325 ½ x 1-¼ in. bolts, flatwashers and nuts. (see page 12)

Pass feed struts (P/N 221491-1) to installer underneath for attachment to feed strut brackets.

Use 3/8 x 2-¼ in. bolts, lockwashers and nuts

Secure feed struts together at center after attachment to feed strut brackets

You have now completed the assembly of the ES45T-T-1 reflector. The next step in the installation is the assembly of the back structure, which begins in the next section.
