Hi everyone,
My FPV drone loses signal and failsafe activates even when it's just a few meters away. I'm using a FrSky receiver and Taranis transmitter. I've checked the antenna connections and everything seems fine. What could be causing this issue?

please specify

Here are the details of my setup:
Frame: Martian II 220mm
Flight Controller: Matek F405-CTR
ESCs: Racerstar 35A 4-in-1
Motors: EMAX RS2205 2300KV
Receiver: FrSky R-XSR
Transmitter: FrSky Taranis X9D Plus
Antenna: Stock FrSky antenna
Battery: Tattu 4S 1550mAh
I’ve ensured that the antennas are connected properly and have checked the orientation. I’ve also updated the firmware on both the receiver and transmitter. Despite these steps, the issue persists.What else could be causing this issue, and how can I fix it? Any advice would be greatly appreciated!
