GPS Signal Lost. RTK Antenna Copper Filament Gone?

GPS Signal Lost. RTK Antenna Copper Filament Gone?

Hello,

I was trying to set up my Yarbo and for a while I had strong GPS and network. Now, I completely lost it. One suggestion was to remove and remaster the RTK Antenna attachments on the Yarbo body. When doing this, I noticed that the copper in one of the RTK towers was gone... I'm wondering if a wire loosened and fell out? Anyone else experience this? I see the copper filament inside the coax attachment of the other RTK antenna tower.
