I've seen many requests for recommending an outside antenna. I use a double YAGI

It is pointed directly at an LTE tower that is 13km away, and I get 100Mbps download speed in the speedtest.

In the mountains here there is only this one tower that is line-of-sight, so a directional antenna seems the best choice.

Now, I have a question for those who know technicals!

I have bought a second LTE router, the MR550 which I will set up on a second LAN in my house, using a second SIM card account.

Can I connect both the MR600 and MR550 to the same set of YAGI antennas?
