Please advise what kind of antenna (Dual MIMO LTE Antenna, ANT-100-LTE4-G?) is used for MAX HD4 IP67 and how many number of such antenna is need. Thanks!
It really depends on how many cellular modems you want to have functional. And the aux/diversity can only help download not upload speed. Personally, on my MK2 deployment, one antenna is fine and I put a terminator on the open aux/diversity port. I really wanted more upload speed but since a second antenna won’t help that I am going to skip.
