The Aomway 5.8G 600mW Transmitter is perfect for those that are looking for a high power output AV transmitter with PWM, especially for long range FPV use.  PWM (Pulse Width Modulation) saves transmitter power and assists in the immunity of signal transmission to interference making it a very desirable feature of this transmitter.
This transmitter packs an awesome punch with 600mW of 5.8GHz power in a conveniently sized video/audio package!  It has adjustable frequency selection with 40 channels selectable so it is  also excellent for FPV racing applications.  A selectable 5 or 12 Volt camera power output is also incorporated in the design all of which makes this a must have for those looking for a transmitter with good performance.
