Re: Wearable option

Hmmm, now how to you transmit out of a metal box? inside a concrete building
with lots of metal.  Great concept, I tried it in the early 80's with 440Mhz
in my high school. I had 25Watts of power in my car outside with a good
antenna and I couldn't get good reception away from a window when i had a 5
watt transmitter with me... Inside of a metal locker.... you wont get more
than 20 feet. :-/ sorry but it's just the mechanics of electromagnetic wave
propagation.. Metal reflects, concrete absorbs, and the metal reinforcement
rod in the walls just adds to the delimma. Now if you can get the school to
allow passive repeater antennas in the hallways....:-)
