Signal-to-noise ratio S(Fo±3MHz): 70dBc Antenna port impedance: 50 Ohms Input voltage: DC7-36V (2-8S Battery) Output voltage: 5V@600mA Antenna interface: MMCX Cable interface: sh1.25 6pin Video format: PAL/NTSC Operating temperature: -10℃~+60℃ Weight: 22g (only for image transmission) Precautions 1. Install the antenna before use. 2. If the image transmission is overheated, the temperature control protection be activated and the power be automatically reduced. Please good ventilation and heat dissipation when using. 3. The 5V output is only used for the camera. It is forbidden to connect the power input to the 5V output port, otherwise the image transmission be damaged. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
