Are the two antennas (R/C link and wifi video mushroom) supposed to be pointing vertical (up), or oriented toward the drone as it is flying? Does it even make a difference? I see on the Yuneec site they are "vertical" but hey, no way of knowing if they are following best practices in a beauty shot... I also have an Itelite DBS range extender that explicitly states it should be pointed at the H while flying because, duh, it's highly directional. Is there any orientation of the stock bits that is better than another? Are there any aftermarket antennas that fit the stock antenna mounts that improve general (not directional) performance (that you as a pilot have used)? My thanks in advance.
