Photo by Aan Nizal on Unsplash Video signal loss during FPV drone flight is a dangerous situation any FPV pilot can experience. Suddenly losing your screen or encountering severe noise can lead to loss of control and even losing your drone. However, this problem is solvable with a clear understanding of its causes and a systematic approach. This guide will help you enjoy stable FPV flight with a clear picture. Video signal loss isn't just a VTX issue. It's a complex interplay of factors, including VTX output abnormalities, antenna malfunctions, frequency interference, poor wiring, and even the flight environment. You need to examine each element individually to accurately identify the cause and find effective solutions. VTX (Video Transmitter) Inspection: Output and Heat Management One of the main causes of video signal loss during FPV drone flight is an issue with the VTX itself. Before flying, if you have an RF Power Meter, measure the actual output of your VTX. If...
