Attach the 144" spreader support ropes onto each spreader rope connection assembly, knotting
through and around the cushioned p-clamp.
Working with help, if possible, using the step ladder positioned near the center of the antenna. Pull
on the spreader support rope to bow the spreader up. The spreader support rope must be horizontal
when the spreader is moved into the final antenna position. See
Figure 18
. Knot the rope through
one of the three vertically aligned holes on the center post support rope attachment hub. Adjacent
spreaders share rope attachment holes on this hub.
Figure 18
Repeat this process on the spreader on ‘opposite’ sides of the antenna until all six spreaders are
secured in their final position. Each spreader end will be at the same horizontal height position as
the rope attachment hub on the center post.
The seventh 144" rope is
strung between the spreader
rope attachment clamps at
the end of the spreaders
adjacent to the feeder
insulator, across the front of
the beam. Secure this rope
into a horizontal position of
about 129” tied length
without
pulling these two
spreader ends together as
shown in
Figure 19
.

Ropes previously installed
from the ends of each
spreader to the center post
rope attachment hub are
not shown in this picture for
