Word to the wise to those adding amplifiers to the TX (controller 5.8ghz) or wifi (2.4ghz repeater and camera). Be aware of the maximum input of the amplifier. Most amplifiers can only handle 20dbm (100mw) maximum input (many much less). It is well known that the controller has two modes CE = 25mw (14dbm) and FCC = 126mw (21dbm). I just finished testing using an RF Power Meter and these power levels are accurate. The published power level for the repeater is 17dbm (50mw). My testing with the RF Power Meter is showing 21dbm (126mw). There is no published power level for the camera. My testing with the RF Power Meter is showing 21dbm (126mw). The word to the wise, for best results and the life of your amplifier, be sure you use an attenuator to lower the power level before input into your amplifier. Happy flying.
