Yes I have the stock Becker radio in my 85 300 SD and have a lot of static and few stations. I had to get rid of my stock power antenna replaced it with a fixed one. I had to get an adapter to plug into the European line to radio. This is the second antenna I have tried and reception is the same. I do notice that when radio is playing if I hold my hand on top of antenna reception gets a little louder and better so I thought it was a poor ground but when I try to ground the radio better makes no difference. I am thinking of trying a whole new line from radio to antenna and get rid of the adpater thinking thats wnere the problem might lie. Or thinking maybe I need a new cheapy radio to get some clear reception if I could just get the closest 4 stations I would be happy do not need anything fancy just so I can hear it nate tne static.
