We all like to push the limits on our personal little drones and one of the most exciting activities you can do is go for a long flight, taking your drone to the outter limits of its range.
This is were range extenders come in handy. These small after market items work by concentrating the signal from your controller into a beam but the downside to this is that you always need to be pointing the controller at the drone. So you may increase the range of your drone but may find that you could drop signal more easelly as you move around at distance.
Here a nice video from youtuber Peter Homer showing us that there is a very clear signal boost when using after market range extenders.
Below we have a real life field test using Signal Booster / Range Extender on the DJI Mavic Pro
