Loosely attach the base plate (26) to the
channel (28). Note: the channel
depth varies according to the origin of
manufacture, which determines whether
or not to use the spacer plate (8).

Position the angles (27) of the mount on the
antenna mounting ring parallel to the antenna
top. The antenna top is indicated by red tape on
the reflector rim. Carefully align the mounting
holes and loosely add the attaching hardware.
Important: Partially tighten each bolt while checking to be
sure that the remaining untightened bolts are not
binding in the holes. If binding occurs, loosen
all partially tightened bolts. Then, slightly reposition the
mount to the reflector and repeat the procedure. If the
mount is improperly positioned on the reflector when
the bolts are tightened, distortion of the reflector
can occur. After the four bolts are partially tightened,
fully tighten them as given in Table 2.
Partially tighten the bolts holding the angles to the
base plate enough to compress the lock washers.
