Transmitter power amplifier, the output signal from BH1415F by 2
SC9018, 2SC3355, 2SC2053 amplified signal can reach more than 500 mW,
adjusting well to achieve greater power. Measured by the pull rod
antenna used to be launched in the open 800 meters above. Uses external
antenna will be launched even further. attention in 2053 need to be
installed and tested at the load connected
