FPV transmitters are the basic requirement for FPV flight as they will transmit the image from your drone's FPV camera to the FPV ground station or FPV goggles. The FPV image is usually transmitted in analog format because this type of video transmission has a very low latency. The allowed transmission power for FPV transmitters on the frequency 5.8 GHz is 25mw. Please pay attention with your selection to how much voltage the FPV transmitter has to be supplied with. You can choose between 5 Volt, 12 Volt or 2-6S.
