GENERAL DESCRIPTION
The CD-45-II Rotator consists of a bell-type rotator,
a metered control unit and the necessary mounting
hardware. The rotator is designed to mount on a
plate inside a tower or on a mast. The rotator unit
must be wired to the control unit with a 7 or 8 wire
cable. The control unit must be placed inside the
house or another protected location.
The CD-45-II now features a NEW 8 pin connector
on the rear panel of the control unit for easy
connection to your cable.
Included with this product are the following:

CD-4511 / CD-4511X
has 110 VAC Controller CD-
45IIX has 220 VAC Controller
Due to the wide variety of towers available, each
installation will have different requirements. The
gauge of the cable to connect the control unit to the
rotator depends upon the distance between the
rotator and control. The longer the distance, the
larger the diameter of the wire required. Various
antennas or beams require different installation
methods. For this reason, the owner must procure
the remainder of the ,components after checking
their compatibility. In general, these will be:
A. The beam or antenna desired and a suitable
antenna mast
B. A tower or other mechanism to position the
rotator and beam for safe and effective rotation
(see CAUTIONS):
C. 7-wire cable to connect the control to the rotator
(see Section V).
D. Coaxial cable to connect the beam to the
communications equipment.
E. Appropriate guy wires as required.
F.
Ground Hardware.
