WARNING
Comply with your local law regulation regarding transmitter power.
Failing to do so expose you to fine nor jail. You're warned.
The F is that
Boosting the RC/Video link of your drone that use 2.4G with directional antenna and powered 4W booster.
Why
I wanted to strenghen my Mavic 1 Pro RC/Video signal reliability as much as I can to avoid drop nor signal lost. I tried to buy an Evolite Kit Plus but they just cancel my order and never replied to my mail... Awesome customer service isn't it. So F it, I'll do it myself.
How
- The booster are powered using USB so bring a power bank with you. The step up will change the USB voltage from 5v to 12v (default voltage of the power supply but range is 6-12v according to the datasheet). Power consumption from the USB socket is around 0.6Ah at 5v.
- You need to open the booster to desolder the power jack connector and replace it with bare wire sticking outside.
- I had to invert the SMA connector side (there's one female and one male) to use the SMA wire supplied with my antenna and the booster. Just swap them. Or buy new SMA cable.
Be aware, booster have direction. You must use it correctly, one end is for the input the other to the antenna (hence my modification at the SMA connector).
End goalDJI Go with FCC Mod
