Query: Static was unbearable.

I live and work in rural Iowa where not all frequencies are used. I tried this unit in 3 cars and in my home. In all 3 cars the static was unbearable regardless of which frequency I selected.The only way this was satisfactory was if I used the battery option and used the transmitter inside my home with the unit right next to the radio.The only reason I gave it a ONE star rating was that ZERO or NEGATIVE ratings were not an option.
