What is a Video Transmitter?
https://www.easytechjunkie.com/what-is-a-video-transmitter.htm
VTX stands for video transmitter, this is the heart of the FPV life system. Pumping life into the many possibilities of FPV. VTXs come in many different shapes, sizes, strengths, and wiring setups. Strapped to the front of the quad is an FPV camera, and strapped to the head is a pair of FPV goggles. You can watch live, instantaneous footage right from the cockpit because the VTX is sending the footage received from the camera out to the goggles.
You are picking the right VTX for you. This will start with knowing if size and weight are factors for you. If you are planning to race, and only race, then you will select any VTX that is light in weight. It’s probably important that your VTX can do pit mode and channel control (depending on which one you choose). This may be a smart audio feature or the tramp protocol. Pit mode is where you will be able to set your VTX to a certain mode that allows you to power up your quad without powering up your VTX to keep you from blasting video and trampling over other racers on the track. Channel control allows you to change your frequency right from your radio for easy switching at a race, or to prepare your quads for the race the next day. Seeing that range is not so much of a factor in a race, only 25mw is allowed, and all that you need. So you can pretty much pick any when it comes to figuring out which is best for you and your power output needs.
