Power Line Adaptors.....

Power line adaptors,...are there any near to you,...If so how do you find it....

These units are used to establish a network within the home, TV and data signals are passed between the adaptors by means of radio frequency energy directly into the mains wiring of that home. The frequency used is 3-30 MHz. The resulting interference extends many 100's of feet from the household using them. This prevents users of the short wave radio spectrum from being able to use their radios. World broadcast stations and many other services are blocked out by the interference.
