The DJI 5.8GHz AVL58 Video Downlink was designed to work with the DJI iOSD MARK II On Screen Display unit and Zenmuse gimbal to provide long range FPV video transmission to the operator. When used with the iOSD module, data including voltage, altitude, distance to home, and other features are displayed on screen. This will work with either a PAL or NTSC video transmitter and overlay all this information onto your FPV goggles or monitor. Simply mount the Wireless Video Link transmitter (TX) to the aircraft and connect the Wireless Video Link receiver to a display screen, and the Downlink will allow wireless video signal transmission. The 5.8GHz Video Downlink features small size, low power consumption and high sensitivity. The product can be used in a variety of applications that require wireless video communication. The Wireless Video Link includes both transmitter (TX) and receiver (RX) modules, working in the 5.8GHz ISM frequency band (5725-5865MHz) with a transmit power of 500mw. Two cloverleaf antennas are included with the Transmitter and Receiver. There are a total of 8 wireless channels that can be selected. These channels are: CH1-5705MHZ, CH2-5685MHZ, CH3-5665MHZ, CH4-5645MHZ, CH5-5885MHZ, CH6-5905MHZ, CH7-5925MHZ, and CH8-5945MHZ.
