FrSky Tandem X20HD: The Ultimate Drone Transmitter

First radio controller with built-in HDZero compatible FPV screen

FrSky Tandem X20HD

FrSky’s high-end X20 transmitter series has 3 versions: Standard, S and HD. The X20HD has a built-in integrated FPV screen (800×600) 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. Before purchasing, make sure you choose carefully between FCC (US) and LBT (EU) because the internal antennas are optimized to be used in these regions.

The FrSky Tandem X20HD 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 edition 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 a separate HDZero video receiver attached to your goggles. Before purchasing, make sure you choose carefully between FCC (US) and LBT (EU) because the internal antennas are optimized to be used in these regions.

The Tandem X20HD radio measures 213x200x95 mm and weighs about 830 grams without a battery. It comes with the ETHOS operating system and supports up to 24 individual channels. With the right radio receiver, you can obtain a range of up to 100KM and down to 4ms end-to-end latency.
