HD Digital Video Transmission System

FrSky Tandem X20 series HD radio system provides the perfect solution for FPV flying and pilots preferring
an easier operation with fewer devices. The HD version of the X20 radio system includes an integrated FPV
screen supporting 720p 60FPS video quality, removing the need for a standalone FPV screen. When
combining the HD 720p 60FPS video with near 0ms low latency digital video transmission technology, the
X20 HD radio will provide more enjoyment and confidence when FPV flying tours. The built-in video receiver
module is compatible with all HDZero video transceiver (VTX) products.

The X20 HD radio package includes a 5.8G antenna kit. The circularly polarized directional antennas ensure
that the radio receives optimum video transmission signals, even in complex RF environments. The HD
version of the X20 radio also provides an HDMI output which can be used to easily transfer the HD video to
an external monitor or device if required, this provides a great solution if you wish to use your existing FPV
goggles which support HDMI-in, removing the need for separate HDZero video receiver attached to your

goggles.
