This course will walk you thru step by step instructions on how to open the DJI smart controller, remove the original antenna and bracket, replace the bracket and install an aftermarket antenna on the controller. This happens to be using the antenna by 4 Hawks but the procedure is the same for most any aftermarket antenna you want to use. THISDOESNOT cover gimmicks such as parabolic dishes. This is a true antenna upgrade which requires extensive work taking the controller apart including removing the batteries, gimbal wheels etc. I have taken care hopefully showing you the areas where you need to pay special attention to such as antenna removal and ufl connector . Special note this will increase the signal strength between the controller and the drone but is also dependent on your environment. You also assume any and all risk of malfunction due to installation mistakes if not done properly. I have also in this course put links to where you can get special tools to perform this mod as well as where you can get this antenna i use in the video. These antennas are usually in high demand so they go out of stock quickly. Please look at my other course available on modifying the DJI drones as well, between this modification and modding the drone itself you would have a pretty robust drone set up.
