Locate the 6m mounting plate (PN 10-1019-31). Using the 1 inch U-bolts (PN 60-0001) as shown in figure
9.11, place the 6m passive element on top of the 6m mounting plate with the slit in the plastic sleeve point-
ing downward. Position the plastic insulator so that it is centered between the two U-bolts. Tighten using
the 1/4” Nylock nuts (PN 60-0030). Be careful not to over-tighten or you will crack the plastic insulator.
Figure 9.10 shows the center-to-center spacing of the 6m passive element. Position two 2” aluminum sad-
dle halves (PN 10-1601-22) on the boom and insert two 5/16” x 3-1/2” hex head bolts (PN 60-0065). At-
tach the 6m mounting plate with the bolt holes for the aluminum saddles facing towards the director ele-
ment as shown in figure 9.12. Secure with 5/16” Nylock nuts (PN 60-0046) but leave loose enough for lev-
eling of the element. Figure 9.14 shows pertinent data for this step.
Place a level on the 6m passive element as shown in figure 9.13. When the position is correct, tighten the
aluminum saddles. Be sure to use anti-seize on the stainless steel fasteners.
