Also I have a question with parabolic antenna if I fly directly above how am I supposed to place my antenna because if I do it how they say in the video than the parabolic will be facing down away from the drone

Hi there, it is not recommended to use the third party accessories as the performance can not be ensured. If you are having issues with the distance, kindly follow the video tutorial below on how to properly position your antennas.Thanks for your understanding.

I've never had the need to install the antenna boosters. On a clear day, I am able to fly a pretty great distance away.
The best antenna position, from what I have found, is to have them at a 45 degree angle out of the controller. So, not straight out, or straight up in down. Right in the middle.
Let me know if you have any other questions!

Hi, Thank you for the additional help and suggestion. Please let us know if you need our help as well. Thank you for the support.

The curve "catches" the signal...so if flying directly above you, rotate your RC so the extenders are "catching"....or reverse the extenders on the antennae and hold the RC flat/parallel to the ground and position the antennas flat/parallel to the ground.  You really don't need them flying 400' high...they're more for flying a long way away from you (probably illegally out of LOS).  

Your "boosters" attempt to make your antennae more directional so the signal is radiated and received from mostly one direction. In this case, keep your antennae perpendicular to the aircraft as in the video, and keep the "boosters" open sides pointed toward it because that's the direction they're trying to focus the signal.

Mine is just a tiny dot, very easy to loose sight of long before it runs out of range.

Trees are pretty opaque to microwave signals like ours.

I've noticed a large distance increase by adding the antenna boosters. I believe about $6 in Amazon.

Range increase and rock solid signal between buildings in a city, in a zone with a lot of WiFi interference.
I’m very happy with them!

Safe Flying.
Alex.
