ABSTRACT:
A method of isolating an appliance coupled to receive radio frequency (RF) broadcast signals from an electrical hazard includes the step of coupling a first and second conductor for providing the RF broadcast signals to an isolation device. The isolation device is coupled to the appliance so that the first and second conductors are electrically isolated from at least one of the chassis and the ground of the appliance. An apparatus for isolating appliances such as community antenna television (CATV) devices coupled to receive RF broadcast signals from an electrical hazard includes an isolation device, such as an isolation transformer. The isolation device is coupled to two conductors provided for receiving the RF broadcast signals. The isolation device is also coupled to the appliance. The isolation device electrically isolates each of the two conductors from at least one of the ground and the chassis of the appliance. The methods and apparatus are particularly applicable for isolating CATV devices (e.g., computer systems, television, radios, videocassette recorders, etc.) coupled to receive RF broadcasts from an electrical hazard impressed upon the CATV coaxial cable.
