Locate:

Two boom-to-mast plates ( Figure 5 )

One 3/8 x 4” fully threaded bolt (EZeye™ bolt)

Three 3/8 x 16x Nylok nut

Two 3/8 flat washer

Four 2” U-bolts with saddles & Nylok nuts

Two 2 1/2” U-bolts with saddles & Nylok nuts
Insert the 3/8 x 16 x 4” fully threaded bolt through the EZeye™ hole in both
mast plates, add nut then tighten (
Figure 6 ), be sure that all the remaining
holes are lined up with each other. Attach the mast plate to the mast (or tem-
porary mast) using the four 2” U-bolts with saddles and nuts. Tighten se-
curely (
Figure 7 ). Thread another 3/8” nut onto the EZeye™ bolt and add a
3/8” flat washer. This represents the first part of the EZeye™ adjustment sys-
tem.
Lift the boom so that the eyebolt in the middle rests on top of the EZeye™
threaded bolt (
Figure 8 ). This bolt can support the full weight of the antenna.
The mast plates in figures 7 - 10 have a different look than what you are actu-
ally given.
Note: If you are doing this on the tower leave the safety rope or cable in
place until you have secured the boom in place with the U-bolts.
Place another 3/8” flat washer after the eyebolt and then another 3/8” nut.
Attach the 2-1/2” U-bolts, saddles and nuts loosely, and then use two
wrenches to “level” the elements as shown
Figure 9 . When finished, se-
curely tighten the nuts on both U-bolts and EZeye™ ( Figure 10 ).
The EZeye™ adjustment system also helps prevents vertical movement of the
elements in the event of high winds!
