Looks like I’m a little late to the party, but the other’s have got you covered. You need to fix that antenna placement. Along the carbon arms is killing any reception you have.
The pictures below aren’t exactly the same, but it’s one of my 5" quads. I run the antenna leads along the arm and then turn them out from the arm. I face the leads pointing in the same direction as the prop is spinning so they don’t get cut in a crash. To hold the floppy wires around I use zip tie and some heat shrink. Simple and it works well.
Make sure the two antennas are at least 90 degrees from each other. If you want best performance with 900MHz they should be pointed straight up and down, and make sure the antenna on your radio is also pointed vertically. (The quad in the picture is on 2.4Ghz Spektrum, but for my FPV gear that gives me more range than I want to walk after I crash into something)
