Chris Anderson has added this forum section for all topics related to antennas and radio transmission.
This will be a great place to see which antenna systems work and which dont work so well. You might want to get as much distance as possible out of each flight or just have that extra margin of safety. Maybe your video isn't all that it could be. Antennas are a key element in your drone system and this is the place to share what you use, find out what others are using, bounce ideas around and find solutions.
