This is why I choose to watch my home movies on my Beta VCR at home, while sipping on Faygo Redpop, and munching on Oatmeal cream pies.

Nice machines! Are the controls softtouch or conventional?

Have you had any interest from schools?

Yeah, most of our work is institutional. i.e. libraries, pre-school through grad-school, courthouses, jails, etc. Most of the schools and libraries want / need radio waves to work, for their wireless networking.

A faraday cage is pretty damn easy to build and the fact that you're working with a very limited frequency range makes it even simpler.
Heck I'd be willing to bet someone has already sat down and worked out a ratio for doing it with just rebar and concrete.

While steel does have some RF insulating properties, the RF box really works more reliably with a higher conducive metal, f.e. copper. For a simplistic description, I would say we basically just use a copper based paint, slathered on pretty thick. (like a light coat of plaster kind of thick.)
