Good day all, i installed the stage 2 antenna kit yesterday from fpvlr which involved opening up the wifi extender to fit the 2 sma cables to the board, the flight i had yesterday was my best with the fvp at the highest preview setting and the whole flight was flawless. Today i went out for a flight and during the pre-flight check i see the radar is pointing kind of north west although i am directly behind it so it should be pointing north. ( 9 sats and all is ready to go) I backed out the app, went back in and still the same so i uninstalled the app, installed it and still exactly the same so i decided not to fly. Back home i thought i'd check the wifi extender sma cables i fitted because i knew they were both close to a metal case on the board but there was a slight gap on both when i screwed it back together, on opening up i see one of the cables is actually touching the metal casing so i realize the one must have moved and now touching, It was a tight fit when i installed them yesterday and was not really happy leaving such a small gap, you see the stock ones come in from the opposite side of the board and have no chance of ever making contact with the metal. I then cut away some plastic casing either side of the extender so that i could route them to run on the outside of the circuit board, now totally secure with no way of the cables moving because it is behind the plastic i'm happy. As soon as i opened the app the radar was perfect and totally true as i already had gps lock, the two flights i had today were flawless and the radar showing true position all the way. So the moral of this story is, MAKE SURE THE SMA CABLES ARE SECURE AND NOT TOUCHING THE METAL CASING AS THIS CAN CAUSE INTERFERENCE! The first time i fitted them and the wrong way to do it. Much better. This may help if you are thinking of upgrading the antennas in the wifi extender or if you have already done it maybe recheck connections and make sure there is no way they could touch the metal. While on the subject i see my wifi extender had shielding between the circuit board and stock antenna but in the videos on youtube there is non to be seen, is this something dji implemented with the vision+'s manafactured at a later date?
