No noticeable difference from interference or local FM or AM signals when powered. When NO power is applied, the signal will be reduced for FM signals. The device must be powered to receive AM signals, which don't "get through" at all. The price is overpriced for what you get. The connector is crimped for attachment (no soldering) and may lose connection with slight tension. I had to recompress to fix the problem.
