I knew they are very directional. I finally put them on Saturday and took it out on my known distance flight. I got an addition 400-500 ft over the windsurfers. Actually, they worked with full signal even 500-600 ft left or right of center about 4000ft out.
On my quads that use 5.8GHZ, these panels actually cut through obstructions a little better that the stock radio antenna.

Flat panel antennas are good for clear areas. They are almost useless with dense obstructions. The signal is very narrow. The stock antennas are multi-directional and better for obstructions especially with the parabolic.
