Tell me where to solder the contacts of the coaxial cable to such a miniature USB whistle?
And what is the best cable to use?
Thank you.

The main problem is that the existing antenna (the path in the form of the letter b in the first photo) is matched with the modem's output amplifier, so if you somehow attach the antenna there, it is likely that you will either not get a result, or, more likely, burn the output amplifier. It is much more reliable to take the modem itself to a point of stable reception using a router with support for 3G modems, a single board computer (Raspberry Pi), or a USB over Ethernet device.
