Review on Foldable Drone Range Extender Signal Booster Antenna - Compatible with DJI Mavic 🔋 Mini, Mavic Pro, Mavic 2 Pro/Zoom, Mavic Air, DJI Spark Remote Controller - 1 Piece by Patrick Martin

RCGEEK Parabolic Reflector First of all I would like to say that it is much smaller than I thought making it ideal for packing the Spark in small suitcases. It fits perfectly with the antennas and is very well made and even comes with its own protective case. The first test was with no reflector and I was able to get out to about 900 feet before the video feed started to break up. I'm in a busy Wi-Fi zone. The second test was with a reflector and I was able to walk further without losing radio control or video signal. 1690 before saying he had a weak signal. This is a must have for any Spark user, even if you don't plan to push it to the limits it gives you peace of mind that you won't lose your video feed up close, which has happened to me a few times.
