tuning clamp assembly. Connect the flattened rod end to the screw on the connector bracket (CB) with nut (11) and washer (41). Attach the entire
driven element assembly shown below to the boom with hardware provided referring to figure F for the
proper location. Slide the poly tube (PT) in the Reddi-Match assembly over the rod (RR) up to the flattened
end of that rod (figure B-2). Adjust to the dimensions
indicated and tighten all connections. Be sure that the
connector is pointed towards the back of the boom and the
Reddi-Match assembly is parallel to the element above.
