TV200 analog TV transmitter is a household analog TV transmitter with adjustable power and frequency,The transmission power is adjustable from 0.5W to 2W, and it can output high-definition 1080 signals or input CVBS analog signals,The maximum distance can reach several hundred meters without obstacles and with the transmission antenna matching the transmission frequency.Input voltage: DC12V, power adjustable between 0.5W-1WInput voltage: DC24V, power adjustable between 1W-2WWhen using a telescopic antenna for transmission, only 12V power can be used and the power needs to be adjusted to the lowest level to function properly Work, when the power is high, there be no display after the first few seconds of startup. Press and hold (Power) when there is no displayPress the (minus) button for 10 seconds and then release it to set the power to the lowest state.
