Due to the poor filtering effect of the video antenna input and the wide operating frequency of the most common 1.2-1.3GHz video receivers. They are unable to properly separate video transmission from 868MHz/915MHz transmission signals leading to interference, and this is where the Flywoo notch filter comes in tackling that interference. This is used on video links to avoid interference from a 900MHz control link. Check out our FPV Wing Gear, as well as the rest of our Flywoo selection! Specifications Small size, lightweight, low loss, imported components, and SMA universal connector. A notch filter suitable for 1.2-1.3GHz video transmission, effectively blocking 868MHz/915MHz signals to prevent interference from remote control transmission signals in video transmission and image quality. Install this notch filter between the video receiver and the antenna, connected through an SMA connector. Weight: 5.2g Includes 1x Flywoo 1.2/1.3GHz VRX Notch Filter 900Mhz - (2pc)
