Hi. I work for a local tv station and i do live video streaming services from churches to studio with my encoder. I need an LTE modem antenna that i can put it indoor by a high window, or outdoor. The problem that i find is that, when there is a large cround,the build in modem of my encoder is difficult to stream back to my studio HQ.There is no signal. I need something with mimo function enabled. What is best to buy: LHG LTE18 or the ATL LTE18? Do they have auto function in choosing the suitable bands?
