The G-2000RC is designed to accommodate large antenna arrays. The
maximum safe load depends on the physical size
of
the antenna, method
and quality of mechanical installation, and maximum wind velocity at
the installation site.
The diagrams below show several recommended installations. Notice
that mounting the rotator
inside of
a tower provides the greatest
support capaci ty, and is
_
preferable for larger antennas or in high-
wind areas. Use our GS-050 or GS-065 Tower
Mount
Bearing
at the
top of the tower (and make sure that the Bearing is aligned precisely
I·
with the center
of
the rotator,
so
the mast is exactly vertical).
If the rotator is mounted alone on the mast above the tower
it should
be as close to the antenna as possible, to minimize the stress on
the
rotator caused by wind pressure against the antenna. This bending
force on the rotator limits the supporting
capacity
of
this
type of
installation to
smaller
antennas mounted close to the rotator. This
method is not recommended
in
high-wind
areas.
Make certain that the antenna attaches to the mast
at
the
center of
gravity of the antenna. That is, the antenna should be balanced, provid-
ing only downward force on the mast (when there
is
no
wind). The
G-2000RC can support up
to
250 kg (550 lbs).
Be sure to leave enough slack in the coaxial cable
feedline
around the
rotator so that it can rotate 370°.
