#1 Philips screw driver and 2 @ 7/16” wrenches.
1. Unwrap all parts.
2. Remove strapping tape from ends of reflector booms.
3. Open the #4-40 x ¾” screws. Screw these into the center of each reflector element with your fingers before
inserting the element into the boom. This is to ensure that all the elements are threaded properly and the
screws start easy. Remove screws from elements.

copper rod sticking out through the rubber grommet in the boom. Repeat for other connector.
7. Insert driven elements in a ¼” hole in center boom. Fix the element in place by inserting a 4-40 x ¾” screw
