to the forum Lynn & Darlene.
One of my post might have been one that you read. There are a few of us that have switched to the Jack antenna.
Like the Jensen, the Jack antenna does not raise or lower, but you can turn it to dial in better reception. I had my dealer install mine, but M109Rrider did his own install and said it wasn't hard to do.
I don't believe there is a fix for the Jensen, at least I have never heard of one. Your best options are to replace it with the standard batwing or the Jack. I believe Prime Time no longer installs the Jensen and has gone back to the batwing on all their new units.
I did replace the tv with a Vizio from wal mart before I replace the antenna. I guess the Vizio has a better tuner than the Legend because it pulled in more stations.
My Lacrosse doesn't come with a stereo in the bedroom or a soundbar, so I can't help you with that. I haven't had any problems picking up radio stations.
Good luck and I hope this helps.
