What customers say
Consumers view the Channel Master CM-9521A as an economical and reliable choice, especially for smaller residential antenna systems. Users frequently commend the mechanical durability of the rotator motor, noting its longevity when paired with genuinely light antennas. Installation is generally straightforward. However, a key point of contention involves the control system's accuracy. Many users report that the rotation indicator drifts or fails to align precisely with the actual antenna position, necessitating manual adjustments. This unit is best suited for its intended light duty; users attempting to handle heavier antennas or operate in high wind areas often express disappointment regarding position holding. Despite accuracy limitations, the CM-9521A offers strong value for its price point as a dependable entry level motor assembly.
