Trying to find a Signal booster kit for LTE-TDD service which operates on 3500 MHz

Hello there;

Firstly I wanted to say that I'm new here so apologies in case that I posted on the wrong section.

I'm planning to buy a Signal Booster Kit for my LTE-TDD Internet Modem located in my house. I checked and I have a very poor Signal strength inside my house(RSRP<-110dB) but outside the house it's almost okay(RSRP<-75dB).

Unfortunately, my service provider gives their LTE-TDD service on 3500 MHz(Band 42). I think I found the Dome Antenna part of the solution on the RfWel Store but I'm wondering if I can find other equipment (such as an amplifier, a Yagi antenna, etc) as well which also work on 3500 MHz.
