I bought a ballistic nylon case for my 780 years ago. I still have it in a box out in the barn. It was pretty nifty and nice and padded. A case like that would be cool for the SDS200
Take a look at the Pelican 1060. Hard case with foam. Big enough
to hold the scanner and antenna. And , I believe its even water tight.
But, you do need to remove antenna, which is not a big deal.
