When I installed mt Cobra in my truck I had to go and get a SWR meter. Then I was looking at that little meter on the left of my radio. I think is said SWR Meter but I can't be for sure because it's so small I cant read it! This is no use to me at all. The SWR meter I purchased from Radio Shack was easy to read and looked good. It's too big to add to to my radio. Do they make one that I can keep attached and not be in the way?
