Increasing the control distance of a 2.4GHz quadcopter?

Question

Radio communication

Bought a quadcopter:
WLtoys V686G for $110, it has FPV and HD onboard camera recording.
I want to increase the control range. Now the visual control range is 100 meters.
I know the frequency of the remote control: 2.4 GHz.
I started by replacing the stock antenna of the equipment with an antenna from a 2.4 GHz 3 dbi Wi-Fi router. The distance increased to about 120-150 meters.
I found the device:

It is positioned as a Wi-Fi signal amplifier.
I think to use this amplifier later for other multicopters, and debug for now on this one.
Actually, the question is: is such an amplifier suitable for a quadrocopter remote control if the frequencies match?
What can be pitfalls? Is it worth ordering?

Answer 1

The best amplifier is an antenna.
On the copter itself, the antenna should also be as efficient as possible. There is another nuance - the high power of the transmitter near the receiver, on the contrary, worsens the connection - distortion of the received signal.
And finally - there will be some loss at the place where the amplifier is connected instead of the antenna. You can manage to make things worse. Here is an example www.lan23.ru/forum/showthread.php?t=4175&s=b0199ea...
And here is an example of a successful antenna connection https://youtu.be/6nViSfck468
