I took mine off and put a shorty, don’t listen to FM or SXM. Having it whip around on the trails gets annoying. But that won’t be a problem for someone who goes wheeling where there’s little to no trees.
You should be able find a shorty that doesn’t flop around. I believe mine is 15” and it doesn’t move. Reception still is not near what you have with the stock antenna. The 50 cal is cool if it’s looks you’re after.
