The Eagle Aspen rotor can power a pre-amp up to 80 mA and 18 vDC. Using this method, the power injector for the pre-amp is no longer needed. Unfortunately the CM7777 does not fit the requirements because it's current is 125 mA. You can still use the Eagle Aspen rotor but you would have to use the method where their are two coax's, which defeats the whole purpose. I recommend sticking with the CM7777 and getting the Channel Master Rotator. The motor inside the Eagle Aspen rotator doesnt look to be as powerful as the Channel Master's.
If you choose to stay with the convenience of the Eagle Aspen's one cable system, it is compatible with the CM0064, CM0264, and CM0068.
