I am runnng six systems in close proximity. Each system has a cellular gateway (Sierra Wireless RV50) and omni directional antenna. I want to know if I can connect multiple gateways to the same antenna? As an amendment to this question, I would also like to know if I can connect multiple gateways to two antennae (i.e. diversity)?
That is kinda expensive box but at least someone is now selling these type of devices to end users.
I suspect you can not hook the antenna together. If it was receive only then you could. The problem will be the transmissions from 1 unit will likely overload the receiver of the second. I have seen devices called diplexers used on amateur radio to prevent signals from interfering but I don't know if these will work on a LTE connection. It is a well known restriction and you have to think cell companies run into it with their cell towers.
