Secure the feed support tube:
1. Attach the lower ends of the feed rods to the feed support 
tube as follows: Insert the ¼-20 × 2-inch hex bolt through the 
tube, and use the hardware shown in Figure 19.
Make sure the flat end of the feed support tube points toward 
the reflector.

3. Attach the flat end of the feed support tube to the rim of the 
reflector, as shown in Figure 20.
