 So that means we can use channel 1 to 11? Would channel 11 overlap into the
2463 MHz range making it illegal to use it with higher outputs?

 Ok, so 30 x 2=60, x2=120, x2=240, x2=480, x2=960. Thanks.

>>

 Ok, so then a 100 milliwatt card would give me 3.2 watts in the same setup?

 So a 100 milliwatt card and a 24 db gain antenna would put out 24 watts and
be illegal right?
