FIMI X8 RC Antenna mod - 5.8GHz 14dBi, 16dBi panel antenna work very well - Test flight Nov 26

After RC antenna modification, did test flight at same place when test was done with stock antenna for comparison. Summary is; 8dBi 2.4/5.8GHz dual band antenna is worse (or at best same) than stock antenna (which is 3.8dBi but FIMI made best matching). 14dBi + 16dBi 5.8GHz panel antenna worked very well. FPV breaks are less than stock antenna (Placebo effect, though). Surprisingly panel antenna showed very long range compared to stock antenna. This test place is not opened and not good for range test and previous test with stock antenna was Test-1 2,100m, Test-2 2,160m where failsafe RTH was activated. Same place, panel antenna worked with 3,594m then failsafe RTH was activated. 66% more range. Although I have no plan to do another range test from top of hill toward ocean where stock antenna + Yagi antenna showed 7,264m and made manual RTH. If I do, may be more range could be obtainable provided battery works well. Timeline is; 0:00 White 8dBi antenna 0:10 100m H, 500m D Yaw rotation – slight FPV break 1:34 100m H, 1,000m D, FPV breaks 2:33 100m H, 1,500m D FPV breaks 3:10 Signal disconnect at 1,500m D during rotation 3:33 Black 8dBi antenna 3:43 100m H, 500m D Slight FPV break 4:25 Failsafe RTH during yar rotation 4:42 Cancel failsafe RTH and yaw rotation 5:09 100m H 1,000m D 5:19 Failsafe RTH 5:28 Cancel failsafe RTH and yaw turn, then failsafe RTH again 6:16 Black 8dBi antenna with Mod DJI parabolic booster 6:27 100m H, 500m D 6:53 Slow yaw rotation – Slight FPV breaks 7:40 100m H, 1,000m D 7:54 Slow yaw rotation – FPV breaks 8:55 100m H, 1,500m D – FPV break 10:30 100m H, 1,908m – Failsafe RTH 11:29 14dBi, 16dBi 5.8GHz panel antenna 11:46 100m H, 500m D 12:03 Slow yaw rotation 12:30 Slight FPV breaks 12:53 100m H, 1,000m D 13:09 Slow yaw rotation 13:35 FPV break 14:03 100m H, 1,500m D 14:30 FPV break 15:20 100m H, 2,000m D 15:40 FPV break 16:25 100m H, 2,500m D 16:36 Slow yaw rotation – FPV break 17:07 RC signal still strong. Auto RTH activated 18:26 16dBi, 14dBi 5.8GHz panel antenna for straight range flight 18:42 FPV screen – Speed x2 21:36 About 2,150m – Stock antenna did failsafe RTH at this distance but panel antenna shows still strong signal 22:45 100m H, 3,594m D - Signal disconnected and failsafe RTH activated 23:31 FPV back at 2,935m D
