I am a big believer in decent range where its stated, so i like to test it myself and then that will be that, no need to try it again (i still need to do an FCC test mind) When i do the proper range testing, its always over 100% rural, after all, that is the basis of the 8km CE and 12km FCC. I always aim for the exact same heading, this being a line of trees, i keep to the side of them and i know I'm on the right heading. The height is also always the same, as is the holding of the RC and i always use the radar, its imperative for any distance testing.
What i will also do is this, once the signal bars drop to 2 i will be constantly micro adjusting and watching the bars because whilst the radar will show what you need to know, its not infallible because there is no vertical alignment.
Also, knowing that at 1500m and at 120m high, the angle is only 4 degrees off the horizon, one will need to hold the DJI RC and N1 flat, certainly once you pass the 2km mark, obviously that's not the case with externally adjustable antennas but the video clearly shows that BOTH RC antennas were at different angles, whilst its not a vast amount, believe me when i say just a millimeter adjustment can throw the signal some.
In the video the RC Pro antennas should have been pointing straight up and the RC held comfortably. Whilst the DJI RC must be held flat once the drone is out there. That right there is a strong base for the test. Thats why this test was flawed from the get go.
Another important factor is that both RC's should be properly calibrated so that the RC indicator on the Radar is green when pointing at the AC, but not just that, it has to be equal, what i mean is, i have noticed that it can be green more to the left or to the right, so this has to be central, once thats done, stick in a fresh battery and send it lol This paragraph is only for what should be done cause it wasn't use din the video, another flaw. |
