Yes I do. I have the YT-100 from LDG auto ATU. It works as intended. Watch those fiddly plugs though. Make sure the grounding is done well.
I use random bits of wire thrown up. It's not as good as a correct antenna or aerial. But so what I got out in minutes of portable operations. I made As is so I'm? having fun.
I live in a flat (Americans read apartment). So no go from home.
