PROBLEM SEEMS SOLVED WITH NEW ANTENNAE
Thanks for the hints. I unplugged the camera and experienced the same as you - permanent low signal warning. I'm guessing that is the reaction of the system to a missing 2.4GHz signal, not actually something that kills the 5.8GHz.
Anyway, got my new antennae and it *appears* that my range is OK again. Could only test it over the residential area where the drone has to compete with dozens of radio transmitters (albeit 2.4, but still a lot of packet data noise). Here at home, it's pretty much back to how it was before the crash. Will test it over open field, away from houses when I get the chance. So far, I'm relieved.
I could not imagine that the antennae could take damage - after all, it's just two coax cables with tiny coils at the ends. But upon closer inspection, I see evidence that the port side legs got smashed into the lower body and were probably bent far enough to make a kink in the cable or to swage the tiny end under the coils - I'm not an HF expert, but I understand that if the length of this bit is off by even a fraction of a mm, that shifts away the resonant frequency, so maybe that's what was wrong.
Bottom line: if anybody else has range issues after a crash, you might want to have a look at your antennae. And please, share your experiences if it helps you, too. Oh, and be careful when installing the new antennae not to bend the coax cables too tightly - seems they're somewhat more fragile than expected. |
