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 , 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 WARNING:This product requires an amateur radio license to operate legally. Please check your local laws and regulations before purchasing FPV 1.2G 1.6W VTX is a low-frequency signal compared to the 5.8G carrier frequency band, has excellent diffraction ability, and has stronger anti-interference and penetration! Wireless receiving images are clearer and more stable, the transmission distance is longer, and it is more suitable for complex actual environments. When using a 5dB omnidirectional antenna, it can transmit more than 5km in an open area. If an external high-gain directional antenna is connected, the distance can reach 10km. Due to different batches, the appearance, color and printed words of the product , which will not affect the use.
