LoRaWAN 3:1 passive combiner

[Gene Smith]

I'm curious if any of you have built a passive 3:1 combiner and couple to sectorized antennas. I'm thinking of getting 4 SMA connectors for the build and encasing in an aluminum case. I would appreciate any thoughts before I spend the $$.

   I am not understanding what you are trying to accomplish.  What LoRa requency range?  900 MHz or 430 MHz.?  What are you wanting to combine? Power dividers are readily available, and I suspect combiners probably can be found, but I have never looked.
