I noticed that if you don’t attach the antenna to the main SMA port, you get no signal. In addition to that, i’d like to ask if the complete signal quality information is built/based on just main SMA port?
Or the signal information is built based on all four SMA ports?
Additionally, i’d like to ask if there are any rules on how you attach the antennas? Are there any SMA ports that are designed for lower bands (800mhz), or higher (1800+2100mhz)?
And the third question, are there any command lines to get the signal information from each port separately?
The first MOBILE AUX port looking from the left acts as a diversity antenna port, meaning it is used to achieve a stronger and cleaner signal when compared to only using the MAIN antenna. If only two antennas will be used with this device, the first AUX and MAIN ports should be used.
The two remaining SMA ports are purely for 4x4 MIMO support. If you’re not planning on using these ports, it is better to cap these ports with 50Ω RF terminators.
Hope this answers any questions!
Thanks for your reply. I actually use 4 yagi antennas, two of them are wideband 698-2700mhz, the main one is 800+1800mhz and the third one is 1800-2170mhz. its a bit complicated.
In that case, it might be best to use wideband antennas for the first two ports from the left, and the other antennas for the ports on the right. However, it’s hard to say which combination will work the best without experimenting with them, as it’s quite an unusual setup.
