You can find this cable on amazon.
I will copy here the solution I wrote to similar problem:
I have had this issue. It is quite a easy fix. Just need to replace the cable. You are in need of SMA female that has 90 degree angle and other end needs to be SMA male. I bought this cable from local hobby electronics shop for about 5 euros. They only had 30cm long version. They also had some 90 degree adaptors for shorter cables but I preferred already factory made cable with correct pins.
Yarbo did send me a replacement but it took ages. I still have it somewhere. If I remember correctly it was roughly 20cm long.
Yarbo wiki has the video how to open the core correctly to change this cable
