ELEMENT CENTER SECTION MOUNTING
Refer to the main sketch (Figures
B) for spacing of the elements. Slide the
x 6’ center
sections inside the boom to element mounts. Mount these onto the boom with 3”” U-bolt assemblies as
shown. Refer to Figure 4 (Gamma Match Assembly) before mounting the driven element and note the
position of the coaxial connector assembly. Space the first saddle 1” from the end of the boom. Again,
be careful not to over-tighten the U-bolts. Line up all the sections after mounting with a level or by any
other accurate means. At this time, refer to Figure 2B and complete the boom guy support system.
Allow 6” of cable for the egg insulator wraps and 16” for the wraps around the boom at the boom
to element mounts. Distances shown should be adhered to plus or minus 1”. Pull the sag out of the boom
by tightening the outside nuts on the guy support, then lock the inside nuts against the guy support.

Assemble the
clamps as shown in Figure 2B. Thread the
machine screw (S21) into the
square nuts
1) only slightly at this time. Refer to Figure 4 (Gamma Match Assembly)
and note the
position of the
metal clamps that will attach the gamma match to the driven position.
Insert the
O.D. x 72” tubing (no slots) into the driven element and director center sections. Slide
on a W58 clamp assembly over each element and tighten slightly.
Assemble the reflector in the same manner by using the
O.D. x 72” slotted one end sections.
At this time, refer to the element length chart on page 7 and set the element lengths. In setting element
lengths, telescope the
O.D. into the
O.D. by equal amounts. In any case, the minimum length
telescoped into the next larger size should be 3”. Measure overall element lengths, then push the
black
plastic caps (PL2) over the ends of the premeasured elements.
