Its performance is very powerful, with four adjustable power levels and a maximum power of 2000mW, suitable for long-distance flight. The transmission signal is very stable and the penetration ability is excellent. MATEN 1.2G 2W VTX selects high-strength aluminum alloy CNC shell to assist in heat dissipation, with a unique appearance design that has stronger impact resistance and better heat dissipation performance. Supports the Tramp protocol and can be quickly tuned using OSD.7-36V wide voltage input, with temperature control protection function to prevent overheating and burning. Supports mounting holes of 30.5x30.5mm (M3). One function adjustment button, two indicator lights, easy and fast operation. Image transmission control protocol Tramp, supporting OSD parameter adjustment. Matters Needing Attention: 1: nstall the antenna before use. 2: If the image is overheated, it will activate temperature control protection and automatically reduce power. Please a good ventilation environment and heat dissipation during use. When the environment is limited, a cooling fan can be installed for image transmission. 3: 5V output is only used for cameras. It is prohibited to connect the power input to the 5V output port, otherwise it will damage the image transmission.
