Antenna helped! I connect to Novatel Jetpack 7730L. The signal quality has improved! If you connect an antenna, the ping is reduced from 100 ms to 20 ms. The download speed has been increased from 25 Mbit/s to 50 Mbit/s. The download speed has been increased from 10 Mbit/s to 15 Mbit/s. The guide states that if you connect two Abrams 10 to the Novatel Jetpack 7730L, they will work together in MIMO mode. As far as I know, download and upload speeds should be the same. I recommend it to everyone who uses such a router.
