af5rn- Sheet metal top for a ground plane? Didn't think about that... I was thinking maybe a removable antenna that can be stored inside of the box when not in use...
Yeah, it would still be removable for storage. But using sheet metal for the top, you can put a BNC connector on it to mount an antenna to (and pigtail it back to the scanner), or you can just use the top as a metal surface for sticking something like the magnetic Valor PMM3B on there, getting much better performance than with a duck.
I agree that there doesn't seem to be any good reason to load this thing up with a woofer, lol. I'm not against good sound quality, but after all, don't you want it easily portable? Just a good quality midrange commo speaker, maybe taken out of an old Motorola speaker enclosure, and some acoustic backing would be fine for most applications.
But again, I like the concept!
