**WARNING** Comply with local laws and regulations regarding transmitter power. Failure to do so exposes you to fines and potential jail time. You are warned. The F is that Boosting the RC/Video link of your drone using 2.4G with a directional antenna and powered 4W booster enhances signal reliability and reduces dropouts. Why I wanted to strengthen my Mavic 1 Pro's RC/Video signal reliability as much as possible to minimize signal loss. After trying to buy an Evolite Kit Plus, which was cancelled without response, I decided to do it myself. How - The boosters are powered using USB, so bring a power bank with you. The step-up converter changes the USB voltage from 5V to 12V (default voltage of the power supply, but the range is 6-12V according to the datasheet). Power consumption from the USB socket is approximately 0.6Ah at 5V. - You need to open the booster and desolder the power jack connector to replace it with bare wire sticking outside. - Be aware that the booster has direction; use it correctly, with one end for input and the other for the antenna (hence my modification of the SMA connector). - Swap or buy new SMA cables if necessary. End goal - DJI Go with FCC Mod - Strong directional antenna - 4W booster per antenna Part list - 1x Third-party directional antenna (Raptor SR, Nanosync, or other) - 2x Wifi signal boosters 4W: https://aliexpress.com/item/32839375464.html - 1x Step-up converter XL6009: https://aliexpress.com/item/32944756517.html - 1x Micro USB breakout board: https://aliexpress.com/item/32622990643.html - 8x Neodyme magnet cylinders 5x3mm: https://aliexpress.com/item/1000007993788.html - M4 screws and nuts Print files - booster-usb-base : Base of the box - booster-usb=top : Cover for the box - booster-usb-bracket-extension-2cm : Extension arm of 2cm (optional) - booster-usb-bracket-extension-1cm : Standard extension arm of 1cm - booster-usb-bracket-base : Plate for the box - booster-usb-bracket-controller : Plate for the Raptor SR plate
