Thank you sir for replying... I get touchy sometimes. In this case I didn't see the joke but I do understand. I might have said the same thing were the shoe on the other foot. You see I made it available to the public against the advice of council. The initial concept was to have a postivie impact upon network security. I hadn't thought of actually selling the thing until it got to be quite popular (3500 downloads last month and 2500 in December).
I'm pleased that the design worked for you. Thirty to forty feet is pretty close to be able to notice much difference. I've got two units that are about that distance apart but there is a stone wall between them and all I do is go from an 84 percent signal to a 100 percent signal.
Try the same expirement at a mile and you'll notice the difference, in a big way.
