Insert the center post with aluminum tube sleeve into the Hexxagonal Hub
. The height of the center
post should be 45" above the top of the Hexx Hub as shown in
Figure 4
.
Hand tighten the upper and lower mast mount hardware on the Hexxagonal Hub evenly, to
position the post
exactly in the center
of the hub. Make certain that the plane of the hub is
perpendicular to the post so the post and hub are concentrically spaced through the hub with the
mast mount hardware equally tightened. Tighten the mast mount bolts progressively, but carefully,
to maintain even spacing between the post and the hub upper and lower mast mounts as shown in
Figure 5
.
The mast mount bolts should be tightened firmly to secure the hub, but not enough to dent
the aluminum tubing. Final position of these bolts is maintained by tightening the keeper nuts only
until the split washers are flat while keeping the mast mount bolts from turning further.
Once assembled, you can use a customer supplied 3 foot tube that will fit over the 1-3/8"
OD aluminum tube that sticks below the bottom of the Hexxagonal Hub and tripod as shown in
Figure 4
, to aid in assembling the antenna system at ground level.
