There are many threads like this comparing ranges between various birds, and various antenna amplifier configurations, but these range numbers are not meaningful unless they are compared over the same terrain and flight path. The flight path is by far the most significant variable for range. Around my home, I never got more than 300 to 400 ft range because of the foliage and hills in my neighborhood, and wifi interference. With new high gain antennas, I only increased my range to about 400 to 700 ft. However, if I drive a few miles down the road and launch from a hilltop with a nice view, I can easily fly 6000 to 8000 ft before losing the link (same antennas but ten times the range). New antennas help, but terrain, altitude, and clear line of sight are everything if you want a big range number.
