Okay, I bit on this one. If it has an aerial then it must be transmitting a signal or RF of some type. What frequency is being used and what is the power level? What about television interference? People are complaining about the smart electric meters need to look into this.
Now many turns of the wire are wrapped around the pipe? Is there a difference between the number of turns if copper or plastic pipe is used. Is there a filter system to remove any residue?
Seems like a lot of money for something so small. I would like to see one in action.
