Issues with rover GNSS signal reception via Ucenter with the Pixhawk 4

Thank you very much for the quick response!

As I mentioned earlier, I aim to automate the entire process in case the RTK station and rover need to reboot at any time, which apparently can only be done through Ucenter.

Holybro had sent me to the following link:
Portable RTK Base Station Setup

In that link, a block entry was also written:
Simple Portable RTK Base Station

Some settings need to be made on the GNSS receiver through UCenter. Therefore I am forced to work with UCenter. Both instances used an H-RTK F9P Helical or a similar antenna which can be directly connected to a PC. However, this didn’t work for me, and my first attempt looked like this.

Would you now suggest I try it this way?

I would prefer to utilize it as in the first variant. Otherwise, I’d have to consistently purchase this additional block, which apparently only intercepts the GNSS data and allows U-center to read it via the USB-C port (blue). Please correct me if I’m mistaken. Or is there an even simpler solution?
