DT-7141HE Mini Transmitter for Drone Aircraft

- - - wireless transmitter receiver

Outline

Dexin DT-7141HE mini encodulator+transmitter is a set of real-time image transmission system which is specially designed for working with mini drone aircraft. It integrates encoder, modulator, transmitter and antenna. It converts the real-time signal from the mini camera into RF and send back to groud wirelessly. The returned signal will be received by the accessary STB and displayed on TV screen. .
