The Tiny Whoop, because it needs to stay very light, is usually limited to a 25mw video transmission. To get more range out of your video signal you can upgrade your goggles/groundstation antennas.
This is the best antenna for goggles/groundstation I have found. It can punch thru multiple walls and dense foliage. If you use this antenna on your goggles. You'll have to get used to positioning your head such that your antenna points in the proper direction, but it's easy.
Designed specifically for the long range wanderer, the Pepperbox offers both high gain (13dbic) as well as wide beam width (180 degrees!). No antenna tracker is necessary for this antenna. Just aim in the general direction you intend to fly and go without worrying about aiming the antenna! Vertical coverage on this antenna is somewhat limited (only 60 degrees) so it is not suitable for high altitude runs.
