I'm going to construct a metal box out 18 or 20 gauge steel or aluminum. Dimensions will be roughly 26" long, 6" wide, and 6" depth (or height).<p>I'm faced with a really difficult problem. Normally, if the parts you put in the box get hot you can exhaust the heat or bring cool air in...

Hello keymaker.<p>Some of my thoughts about a amplifier for a cordless phone that could provide enormous range, are the same as yours.<p>You wouldn't want a gizmo like that next to your brain!! Building a mobile base station would be the only sensible thing to do, as you said.<p>Thanks for your repl...
