FrSky Tandem X20HD Dual Band Transmitter with Built-in HDZero Receiver, 720P 60FPS FPV Screen

Overview

The FrSky Tandem X20HD is a dual band transmitter designed for FPV pilots who want fewer external devices, featuring a built-in HDZero receiver and an integrated FPV screen. It supports 720P 60FPS HD video and near 0ms low-latency digital video transmission, and the built-in video receiver module is compatible with HDZero video transceiver (VTX) products.

The X20HD package includes a 5.8G antenna kit. Circularly polarized directional antennas help maintain stable video reception in complex RF environments. An HDMI output is provided for sending the HD video feed to an external monitor or HDMI-in compatible FPV goggles.
