jittena Drone WiFi Extender, Long Range Drone , DJI Mavic Pro Controller.

At first I was skeptic about it, but I was right. It does not work. The picture shows the flight record and how far I was able to go with and without the antenna. With the antenna 1345 meter and without 1277 which is only 68 meters difference. And some factor may have just change which is why it's only a little further.

I have to say I am rather impressed by these little things . They really do work quite well .I am able to get a much further range with my Mavic Pro when using this product which beats paying $300 to have my remote control upgraded by drone world to get a longer range antenna .

Works so well I bought 2 more for my spark and mavic air

Not spectacular, but it does seem to improve the range some. It's hard to tell exactly how much it does help because I've only flown in the city with it and there is alot of interference in the city. If I have a chance to use it in the country, I will update my review if I see significant improvement where there is less interference. It's a nice low price, so any signal improvement at all is worth what this product costs.

I'm on the fence about this one, I have a Mavic Air and it seems though it was causing some interference though. I'll retest it and update my 2 stars.

Bought it as a Christmas gift to my father, he likes it.

These give me improved range without having to take apakrt the controller! A must have for any drone enthusiast

Mavic Air で使っています。装着時に４回飛ばしてどれも3,200〜3,500[m]あたりで画像がカクカク。未装着時にも４回飛ばして2,200〜2,500[m]でカクカクでした。効果ある気がしますが、商品説明通り1.4倍の電波強度になっているのか疑問です。
