  Get a radio licence so you can pump out as much as you want.
  Or who is going to know how much your output is, I anybody asks say you have 20mtrs off lmr * hidden.

    1 x 10 x 10 x 2 = 200?

    Amplifier Safety

    Every 10dBi of antenna gain gives you 10 times the power.
    Every 3dBi of antenna gain gives you double the power.

    Connecting an ampl! ified card or AP to high gain antenna is not only
    illegal, it is dangerous.

    Why?

    A 1W amp into a 23dBi antenna would give you:

    1W x 10 (for 10dBi) x 10 (another 10dBi) x 2 (for 3dBi) = 300Watts
    EIRP at the antenna.

    Scary.
