Due to the wide working frequency and poor filtering effect on most common 1.2-1.3G image transmission receivers, the video signal and the remote control signal cannot be effectively separated when collocation with the 915/868 remote control system, resulting in the image transmission picture is often disturbed.
By installing this filter between the 1.2G VRX and the antenna, the 915/868MHz signal can be effectively filtered out, and the signal quality of the 1.2G VRX can be improved, making the video picture cleaner.
