FEED INSTALLATION
1.
FOCAL LENGTH -
As shown in figures 5 thru 7, attach the feed horn assembly
to the three feed rods with the same 3/8" hardware as above. (For ku-band
single pol only, insert the feed cover tab (item #7) between the feed horn and the
3/8" nut). Tighten the three bolts securely at this time. Check the focal length by
measuring from the face of the feed horn to the reflector cover plate as shown in
figure 8. If the focal length is incorrect, adjust the feed clevises in or out at the
reflector surface as needed. Be sure that the clevises are adjusted equally.
When the focal length is correct, tighten all feed support and clevis hardware
securely. The focal length is 35.8 inches.
