ASSEMBLY OF DRIVEN ELEMENT

Install the two driven element clamps (Item 40)
on the boom sleeve (Item 22) and Boom No. 1
(Item 15) using a single 10-24x 2 inch bolt (Item
45) and a No. 10 lockwasher (Item 62) and 10-24
hex nut (Item 54), as shown in Figure 4, Detail
A.

Install the two DE halves (Item 25) into the DE
clamps using 10-24x1 inch bolts (Item 49), No.
10 lockwashers (Item 62) and 10-24 hex nuts
(Item 54). The overall length of the DE should be
38 inches (965 mm). Tighten all hardware
securely.
Install the T-match tubes (Item 26), and T-match
straps (Item 41) using 1/4 inch and No. 10
hardware as shown in Figure 4, Detail B. Do not
tighten hardware at this time.

ASSEMBLY OF OTHER ELEMENTS

Select the reflector element 3/16" x 39 3/4"
(Item 1), marked with two black bands near one
end. Also select two (2) insulators (Item 34) and
two (2) pushnuts (Item 52).

Push one of the element insulators onto the
reflector, so that it's inside shoulder is 19 5/16
inches (491 mm) from the nearest end.

Insert the long end of the reflector into the
mounting holes on the #1 boom section, as
shown in Figure 5. Slide another element
insulator over the other end of the reflector, and
push it onto the element until it seats into the
mounting hole. Recheck the exposed length of
the reflector and reposition if necessary.

Carefully slip the 3/16 inch pushnuts (Item 52)
over each end of the reflector and push them
along the element until they are snug against
each element insulator. Check the exposed length
of each side of the reflector after this process to
ensure the correct dimensions. Remove any metal
shavings which might short the element to the
boom.

NOTE: You may wish to use a hollow
handled nut-driver or the short length of 3/8
inch tubing (Item 67) to help push the
element insulators and pushnuts onto each
element. If you accidentally slide a pushnut
on too far, then you should cut it off the
element and try again with one of the spare
pushnuts.

Select one each of elements - Dl, D2 (Items 2
and 3). Identify these elements by the length and
color bands listed in Table 1. Install these
elements on the #1 boom in the holes shown in
Figures 3 and 4, using the insulators and
pushnuts and methods as described earlier.

Select one each of elements - D3, D4 (Items 4
and 5). Install these elements on the #2 boom in
the holes shown in Figure 3.

Select the remaining elements - D5 thru D13
(Items 6-14). Install these elements on the #3,
#4, #5 and #6 booms in the remaining holes as
shov;n Figure 3.

After the installation of all elements check each
exposed length from Table 1. Also check to
make sure the elements are in the proper order
on each boom section. If any element has to be
adjusted or moved, there are extra pushnuts
supplied for partial reassembly.
