Archerotor Antenna Rotator (150-1225) Hints and Tips Faxback Doc. # 17025 This unit does not have a circuit breaker nor a user-replaceable fuse. It has a fuseable part (since the Archerotor is UL-listed), but it is not user-replaceable. The antenna rotator that RadioShack sells should not be used for communication antennas. The braking system in the rotor will not handle the wind load of large communication antennas. RadioShack sells through the RSU division specialty High-Gain Antenna Rotators for communications antennas. (IR-10/18/96)
