The FCC regulations for PtMP and PtP allows only 30 dBm (1 watt) EIRP in the UNII-2 band. This is 24 dBm (250 mW) into a 6 dBi antenna. If you use a 10 dBi antenna, you must limit your transmitter (or amplifier) to 20 dBm (10 + 20 = 30 dBm). For a 15 dBi panel antenna, this allows a 15 dBm transmitter (or amplifier). Power is measured at the antenna connector, so subtract any cable loss between the amplifier and the antenna.
