1: Stable output of 1.6W power for a long time, without the problem of power drop due to excessive temperature 2: Fully surrounded by a metal shell, compared to the VTX of its peers where the entire component is exposed, it has an excellent shielding effect, preventing the VTX from being interfered and enabling a longer transmission distance 3: You can adjust the frequency of 8 channels through buttons, which is faster and easier Model:1.2G 1.6W VTX Output power:1.6W Transmission distance(No interference at the beach):15KM Input voltage:DC 10-12V Rated current:12V/330mA@1.6W Video format:NTSC/PAL Output frequency:8CH (1080MHZ 1120MHz 1160MHz 1200MHz 1240MHz 1280MHz 1320MHz 1360MHz) Parameter adjustment :button Indicator light:digital tube (4/5/6/7/8/9/A/B) Microphone:None Image transmission protocol:None Antenna interface:SMA Working environment temperature:-20-60 Installation hole position:none Model:1.2G 1.5W 12CH VRX Mediation type:FM Receiving frequency:12CH,910/980/1010/1040/1080/1120/1160/1200/1240/1280/1320/1360(MHz) Receiving signal:simultaneous transmission of audio and video Receiving sensitivity:-85dBm Video input level:1Vp-p Audio input level:1Vp-p Working temperature:-20-+50/-4H-+122H Working humidity:85%RH Storage temperature:-40-+80/-40H-+185H Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.
