Case for the Droid X I can slide phone into that allows for normal use?

[xmguy]

I'm building a FM antenna rig. I need a case to mount the antenna to. I has to be a plastic hard shell case so I can mount the antenna. But since it's not for protecting the phone and it won't always be in use I need a case I can slip the phone into and use it for the time and remove it without lots of complications. Or a 1 piece deal that it easy to place in the phone and remove. Ideas?
