INSTALLATION:
The KENROTOR
KR-600RC can be mounted on a mast top
of a tower or inside tower.
It is designed for use with medium-sized antennas.
The maximum load. capability of a rotator is quite
dependent on the physical size of antenna, mechanical.

ty.
Illustrated in Fig. 6 and 7 are the result of our
long field experience and accurnulation of know-how.
An Antenna should be mounted as close to the rotor
as possible. Wind pressure against the antenna
produces a bending force on the mast which is
proportional to the length of the mast used- we
suggest three feet of antenna support pipe as the
practical timit.
Vteight of the antenna should be balaneed on either
side of the boom at the mast-to-boom clamp.
Balanced weight produces only axial down thrust on
the rotor and our KR-6O0RC
has the axial load rating
of as high as 440 Lbs.
Unbalanced installation results in some leverage
force which strains the mast at the clamping point
on the rotor. Great care to be given especially in
high wind areas.
