maximum wireless distance?

whats the maximum distance, i would like to transmit over 1 mile or less , bout half a mile
i herd this can be done with an old satelite box? dont know if this is true!

depending on the antennas used and the radios, you can get some distance. but trying to keep indoors with stock antennas, youll have trouble. if you can keep line of sight, a mile is easy, long as you have directioinal antennas and the power, 100 mw or so hould do it plenty fine, with a couple 14 db antennas.
