Maybe a solution you don't want to hear,but what I did was got Sirrus (bottom of the line)radio and it transmits to the radio on preset frequency's.I pay 8 bucks a month for 50 channels and my reception is better then switching and searching for another station as I move thru areas.Sat antenna mounted on top of RV,cord down thru front roof vent.Only paid 39 for the radio,so a fairly inexpensive fix,and the al la carte plan is month to month so no long term commitment.If you go this way,make sure you get Sirrus,the other company doesn't support the al la carte plan.Hope this helped.
