Beyond Line of Sight FPV
What is it?
This is where you, the pilot, are not able to able to visibly confirm the position of the vehicle. This usually implies that there is some kind of obstacle blocking the view of the pilot. There are different things that can effect how well the signal is able to get around the object without losing signal. Lets talk about two things that you can do to extend your fpv range or get a strong signal despite being behind obstacles.
