RG11 will give you better signal readings - but its expensive as hell. 235 feet of RG6 should not be a problem - at least for signal - not sure about the motor control voltage though - but in theory
C-Band actuator arms use 36 VDC and this voltage seems to travel along miles of cable without any problems. Set the motor up first by carefully following
Sadoun's instructions on the website.
