    so how did they overcome the earth horizon limitations?

  2. Isn't this in violation of FCC Part 15.247? by GMontag · · Score: 5, Interesting

    (b) The maximum peak output power of the transmitter shall not exceed 1 Watt. If transmitting antennas of directional gain greater than 6 dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.

    I am just guessing at what they mean in the article by "high-gain". They say they are using a 1 watt bi-directional amp. My personal definition of high gain is a lot higher than 6dBi.

    Am I misinterpreting this?
