The FLARM BOOSTER amplifies the 868MHz antenna signal by +17dB, and also increases the transmit signal of the FLARM device by17dB, increasing the monitoring range of the FLARM device by about 5 times.When the TX transmit power is greater than 23dBm, the AGC Function will be activated to attenuate the TX gain to stabilize the TX transmit power. Built-in SAW Filter, no need for external filter. The working power of the Booster is DC+5V~+24V, which can be powered from the DC power socket by the power adapter, or can be powered from the FLARM RF port by the Basi Tee.
