Analog video transmitters (VTxs) are devices that are used to transmit video signals wirelessly from a drone to a receiver, such as a display screen or video goggles. Analog VTxs operate in a specific frequency band, such as 5.8Ghz or 2.4Ghz, and use an analog signal to transmit the video. These transmitters are often used in FPV (first-person view) drones, as they allow the pilot to see what the drone is seeing in real-time. There are a few different types of analog VTxs available, including those that transmit a single channel of video and those that transmit multiple channels. It’s important to choose a VTx that is compatible with your drone and the frequencies allowed in your region. In addition to the VTx itself, you’ll also need an antenna to transmit the signal, which should be chosen based on the type of VTx you are using.
