ImmersionRC rapidFIRE module - flight test behind trees

This was my third day with rapidFIRE. The most important thing is the calibration !!! The first two days I was flying with "stock" calibration from a manufacturer. Then I made new calibration and from this point, the rapidFIRE is working like a champ. I used 800mW and R2 (antenna tuned 5600-5745 = 1.1 VSWR) the 1st spot with trees - 340 meters away from me !!! the 2nd spot with trees - 430 meters away from me !!! the 3rd spot with trees - 870 meters away from me !!! The black-white breakups (whole images) was not that visible in goggles. DVR is worse than actual live feed.
