How to extend the usb cable from the lte antenna?

Question

USB

Good afternoon!
Outside the window is this antenna:

From it comes a cable literally 1.5 meters to the router (in the attic). Unfortunately, frosts begin, the attic is not insulated, and in winter the temperature there can reach -30 degrees Celsius. Therefore, it was necessary either to assemble the box, which is inconvenient, or, which is more logical, to lengthen this one and a half meter cable and let it go down. You need to lengthen it by 10 meters, exactly as much is needed for the router to stand in a comfortable, warm place. First of all, I bought an active usb cable 10 meters, which, of course, loses the signal. In any case, if you connect a USB flash drive to a computer, he sees it, but if you connect that one and a half meter cable to mom, and dad to the router, the router does not see anything. The question arose: how do people lengthen such cables? There is not much information on the network, in general they are soldered by inserting a twisted pair cable between usb ports, but there are plenty of comments with bad reviews.
Thank you!

Answer 1

Usb does not lend itself well to elongation. You will need some kind of amplifier. Perhaps you should just install frost-resistant equipment?

Answer 2

Close your modem in a steel box with a 100W bulb

Answer 3

In this case, it is not the USB cable that is being extended.
Options 2. A hermetic cabinet or outdoor router is placed in the attic, from which a twisted pair cable (internet wire) is already stretching where it needs to be.
Option two - use a signal amplifier from which a television-type cable will go down.

Answer 4

As an option, place active USB hubs along the cable path every 5 meters (despite the fact that the cable is of high quality, otherwise more often), but these are additional points of failure.

Answer 5

A box with a light bulb is a good proven solution. But we must not forget to turn it off for the summer, otherwise the router can fry.
You can also stuff it into a soup thermos (if it fits), and insulate the wires. Or make a box out of styrofoam. The router itself generates a lot of heat, if it is insulated, it will not freeze.
