HAM IV / HAM IVX

Antenna Rotator

HAM IV has 110 VAC
Controller HAM IVX has 220

INSTRUCTION MANUAL

GENERAL DESCRIPTION

The HAM IV rotator consists of a bell type
rotator, a metered control unit and the necessary
mounting hardware. The stock HAM IV is
intended for in-tower mounting on the base plate
which is part of the tower. However, in some
instances, mast mounting is desired. The Lower
Mast Support Kit, PN 51467 10, contains a lower
mast support and the necessary hardware to
facilitate mounting the HAM IV Rotator on top
of 

mast.

The rotator unit must be wired to the control unit
with an 8-wire cable. The control unit must be
placed inside the house or other protected
location. Included in the shipping box are:

A. Instruction Manual

B. Rotator Unit

C. Controller Unit

New features in the HAM IV include an 8 pin
Cinch connector on the rear panel of the control,
a chassis ground connection on the 110 VAC
model, and a locking CinchTM connector at the
rotor unit.
CAUTION

When using the lower mast support, antenna
size is restricted to 7.5 square feet of wind
surface area

E. Connector Parts Pack

Due to the wide variety of towers available, each
installation will have different requirements. The
gauge of the 8-wire 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.
