How can DJIs drones and other competitors fly several miles away from a controller with two small antennae while retaining the signal?
In: Technology
Different kinds of signals travel different distances.
Radio isn’t like WiFi. With WiFi, you leave the house and you don’t have a signal. With radio, you can be hundreds or thousands of miles away and still get a signal. They’re using different kinds of electromagnetic radiation.
Also, there’s not only the small antenna on the drone. There’s ALSO the transmitting antenna, the source…that matters too. If it’s super powerful, then it doesn’t matter if the receiving antenna is small.
