#2 - ELEMENT ASSEMBLY

Slide the four pieces of the Reddi-Match assembly (RR, PT, RT, 251) together (figure B).  Assemble the tuning strap onto the element tube (EB)
using the two Reddi-Match clamps (921), lock washers (41), flat washers (941), and hex nut (11).  Slide the Reddi-Match assembly through the
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.
Press end caps (53) on EB.

Check all element lengths using table A.  The cutting
tolerance on these element is 

±

1/16" (.16 cm).  The

elements are progressively shorter as you proceed to-
wards the front end of the boom.  Attach each element to
the boom per figure C referring to figure F for proper
location.
