Easy to use, all in one system that will enable the rotation of an outdoor antenna from an indoor control
box and a hand held remote control. The indoor control unit has internal memory which will allow the
user to auto tune an antenna to rotate up to 69 pre-programmed positions.

The Channel Master system can be specifically helpful to those who use a single outdoor antenna, but
are able to receive signals being broadcast from towers in different directions. In addition to TV antenna
use, the 9521HD is also popular among HAM radio operators and hobbyists for miscellaneous uses
requiring remote rotation. The motor and control unit are connected via a 3 conductor wire that carries
the electrical voltage and control signals from the indoor control unit to the outdoor drive unit.
