1: Stable output of 1.5W 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 Receiver parameters: Working frequency band: 1.2G/1.3G Channel selection: 12 channel selection, digital display Sensitivity:-92dbm Unobstructed range:2KM (actual distance is affected by the environment) WARNING This product requires an amateur radio license to operate legally. Please check your local laws and regulations before purchasing Summary: FPV 1.2G 1.5W 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, there may be differences in product appearance, color, and printed text, which not affect the use. Colour:Silver Material:Aluminum alloy Package Contents: 1x receiver kit 1x transmitter kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
