for Mavic Pro, RC signal is much weaker than video in my experience, and RC signal only work on left antenna.
So, I add a sunhans 2.4g 3W booster at left antenna and use a no brand china antenna (cost $50 usd)
sunhans 3 watt boost is usb power by the remote controller usb port (5v)
result : 3km with full signal at high congested wifi city
