> when the broadcast doesn’t even make it through my walls. But you don't know. If it's radiating a few milliwatts (or even microwatts), that's sufficient signal to be hear across town in a sensitive receiver. The really sad thing is that the unwanted signals could well be stronger than the unwanted one due to unknown resonances in the antenna wire, etc.
