6. Place the lower mount bracket on the lower supports of the two closest tripod legs. Center
the mount bracket evenly between the two legs. Use a level to ensure the mount bracket is
level. Secure the mount bracket in place with two U-bolts, flat washers, lock washers, and
nuts. It may be necessary to rotate the U-bolt so the ends of the bolt pass through holes on
different rows in the lower mount bracket. For tower assembly, use the two U-bolts to
attach the lower mount bracket to the tower legs at the point that puts the angle of the
mount arms at 45 degrees.
