I think it's my wind surfer. It's made from a small aluminum treats canister and soda can gorilla glued in it. I guess I don't know what the range is without wind surfer. I made one from day one. For many years I've been made wifi parabolic boosters for the home wifi. I also think its do to my flights being down rivers and lakes where the terrain works as an additional parabolic antenna. It's not flat and there are thousands of pine trees. I also think if I could go over 400 ft up I could go further not even getting break in video till 10,000 ft.
