How the Walksnail Ascent VRX digital video receiver works

The receiver picks up a digital radio signal from the video transmitter (VTX) of the Ascent system in the range of 5.725–5.829 GHz. It decodes the signal and outputs the image via HDMI at up to 1080p at 60 frames per second.. Two omnidirectional antennas with left circular polarization (LHCP) provide minimal signal loss and reliable reception at distances up to 6 km.

Built-in automatic frequency switching function guarantees a stable signal even in noisy environments. The receiver is equipped with a microSD memory card slot, allowing you to record real-time video without an external DVR. Power is supplied via a DC 5.5×2.1 mm coaxial connector with a voltage of 7.4–25.2 V, which allows it to be connected to 2–6S batteries.
