CHAPTER THREE
SECTION 3.0
DIRECTOR 1 EHU (continued)
ATTACH THE ELEMENT MOUNTING PLATE—DRIVEN (continued)
Locate the element mounting plate (PN 10-1605-11) and insert four 5/16” x 4” hex head bolts (PN 60-0066)
through the plate as shown in
figure 3.03
. Insert two of the 2-1/2” aluminum saddle halves (PN 10-1601-
41) onto the hex head bolts and place on top of the boom on the 2-1/4” section as shown in
figure 3.04
.
The upward lip of the mounting plate should be facing towards the Reflector side of the boom as shown in
figure 3.05
. Securing the element mounting plate with a clamp is highly recommended, especially if there is
only one person doing this step.
Figure 3.06
shows the clamp in place with the upward lip of the mounting
plate facing the Reflector side of boom.
Figure 3.07
shows how the two reinforcing plates (PN 10-1606-01) will be positioned underneath the ele-
ment mounting plate. Place two of the 2-1/2” aluminum saddles onto the 5/16” x 4” hex head bolts, follow
with a reinforcing plate on the bottom of each saddle as shown in
figure 3.08
. Attach four 5/16” Nylock nuts
(PN 60-0046), but leave loose. Be sure to apply anti-seize on each stainless steel fastener. Note that the
1/4” aluminum spacers (PN 10-1613-11) are in place as shown in
figure 3.09
and the outward side of the
reinforcing plates have not yet been fastened. This will be covered in a later step.
Figure 3.10
shows the completed element mounting plate attached to the boom. The clamp has been re-
moved for clarity, we recommend you keep it in place until later in the assembly process.
