6 Home Signal Distribution Kit Installation Guide
Slide one of the U-bolts through the holes at the top of the mounting bracket.
Then slide one of the mounting brackets over the two legs of the U-bolt.
Next, screw the hex nuts on each leg until they are snug. Do not yet tighten the
hex nuts beyond finger tight. Repeat this procedure with the other U-bolt. When
all the hex nuts are snug, verify that the antenna is facing the correct direction
and begin tightening each hex nut with a 3/8” wrench. Turn each hex nut one-half
turn and then move to the next hex nut repeating this one-half turn pattern until
all the hex nuts are equally tight. Tighten the hex nuts enough so that the anten-
na is secured to the mast or pole, but do not overtighten them.
