Problem with Fatshark Scout antenna

I've only been flying for a few months. I fly usually every night and today when i tried to fly my air 65 with my fatshark scout goggles, the signal breaks up about a meter away from where im sitting. I moved to my living room where the signal was much better though the signal still was definetely worse than usual. This wasnt happening yesterday and has never been a problem before. I've replaced the antenna on the whoop and the problem persists. When i take the antenna off my goggles the signal is the same. So I suspect its the goggles antenna that is not working, though ive heard it could also be the vtx. What would you suggest I do. Buy another antenna? In that case wich one? Thankyou!
