I was designing for a chassis that could only accommodate a barrel plug anyway, so they were a good match for my project. I designed with a floating ground that ends up being tied by other connections, so both terminals of the barrel connector are AC when referenced to ground. It's been a tricky challenge and I might abandon that approach (meaning I'll need a new chassis).

One leg of the barrel could be grounded, or you could take a more "pure RF" approach and just have an earth tag that you can attach a counterpoise to.
