RC control distance

[gusri.candra]

Hi All,

Is the actual RC control distance is 7km..? How about in the area that there is some obstruction. I experienced it is only 1km. A bit dissapointed with DJI as there should be at least say half of it.
Any trick to have better coverage..?

7Km is line of sight under ideal conditions and many people have gone out that far. If you have obstructions it can drastically make a difference. You can be 500ft away and move behind a building or dip below a mountain and the signal is gone. Trees and bushes will have a less dramatic effect but will cut down the range by a few Km.

Marginal improvements can be obtained with mounted antenna reflectors and more substantial improvements with expensive external antenna kits that require modifying the transmitter by adding jacks for the antenna. Also note that this will make your signal much more directional so you need to have the antenna pointed at the craft.

Most drones and DJI craft in particular use 2.4ghz and 5.8ghz for control of the drone and to stream live video. Its fairly cheap to use and manufacture, BUT it has serious limitations and drawbacks. If you have perfect line of sight its all good and well... But be warned.... These frequencies go all funky if it has ANYTHING going through its path between the transmitter and the receiver. So flying behind a tree, a building or even a telephone pole at a distance, could give u a break in transmission. In the Phantom 1 and 2 days we had no apps... We relied on live video feed from the craft. If you lost comms there was no app that crashed and caused u to loose communication with the drone. So.... At ALL times ensure that u have line of sight comms with the craft. If u want to orbit objects make sure ure high enough to get the shot without loosing sight of the drone. If u have to be behind something ensure u are close enough to minimise the risk of loosing comms. also remember that Cellphone towers transmit on 2,4 to 5Ghz range - as does LTF TV towers. I have seen drones going bananas when flying close to a cell tower. These frequencies are also very easily bounced. Meaning flying near a metal object can be a risk. many pilots do not understand the intricate channel hopping that goes on when you fly as the drone tries to communicate with transmitter and the app to get a clear frequency to operate on. Just be warned its not a fool proof system
