How To Increase the range of your drone

The range of a drone is determined by the maximum distance of the link between the radio control, considered as a transmitter and the receiver on board the drone. Past this constrain, the intrusion of the connect makes it inconceivable to pilot a drone and comes about in either a crash or the activating of the programmed return to the beginning point, for an air ship prepared with this security framework and pilot assistance.

Increasing the extend of a drone subsequently makes it conceivable to progress the remove at which a ramble can fly whereas remaining beneath control, but too to boost the flag quality, which decreases the number of conceivable outcomes of cuts and obstructions related to the geographic environment or human action. The obligation to have a great deal of knowledge in electronics makes modifying the scope a domain a priori reserved for amateurs of DYI drones, manufactured by themselves, especially since the post and electronic communications code requires the use control systems capable of transmitting in 2.4 GHz, with a maximum power of 100 mW. It should also be remembered that the DGAC regulations concerning the use of radio-controlled civilian drones in the airspace indicate that a drone pilot must remain in direct view of his aircraft. On the other hand, the presence of a second person is essential in the context of an immersion flight with FPV goggles, for which the piloting is done with the live video feedback from the on-board camera.

The different elements influencing the scope

Model aircraft devotees have nowadays embraced the 2.4 GHz frequency band and steadily deserted the ancient frameworks. This choice works very well, but can also show its limits due to sudden cuts in special conditions during flight time, which results in loss of control or an emergency landing of the drone or mini drone.

To cure this issue in hone, it is conceivable to intercede on the radio wires (the most and/or the auxiliary) of the radio control ,replacing those already installed by models with a higher gain, which makes it possible to switch from a power of 2 DB to 5 DB, a priori without having to embark on more complex modifications. It is also conceivable to use a signal amplifier, or booster, by simply installing it in place of the main antenna when the hardware configuration allows it.

Another conceivable adjustment, to access very long signal distances, switch to a UHF (ultra high frequency) system , knowing that the latter has the disadvantage of being able to jam the signal of other drones and of being able to be disturbed by certain domestic equipment. Overflown during the flight time. Be careful, however, to respect the regulations in force for drones, the so-called “Long Range” flight being prohibited in France.

The range of the best-selling drones

Buying a new drone permits you to know precisely it’s extend, since this data is efficiently given by the manufacturer. Here are some examples of the range of drones that have become safe values, mainly for aerial photography: the Hubsan X4 FPV quadcopter, ideal for novice pilots displays a range of 300 meters, the DJI Mavic Air drone can move away trouble-free up to 4 km, just like the DJI Phantom 4, while the Parrot Bebop 2 FPV drone has a radio range of 2 km.
