I bought it exactly as it was necessary to have a telephone line. It works with a MIMO antenna, but in principle, reception is the same with standard horns. The only thing for which a directional antenna is needed is to direct it to a tower that is less loaded. And in my case, this is not the closest tower with an ideal signal. And regular antennas cling to the tower with the signal indicators higher. And the fact that there the speed is 10 times lower than the router does not care. It is also convenient that you can choose the standard 3G or 4G, for example, in 3G 10-20Mbps and on 4G 2-3Mbps.
