In community someone indicated that Cisco IR829 uses both LTE Antenna Main/AUX to receive traffic, but use only main to upload traffic. We currently have a IR829 configured working with Main Antenna connected via controller 0 and interface cellular 0/0. My question is, do we need to do any configuration to interface Cellular0/1? does it need to be shutdown? or leave it in its default configuration (no shut) to receive other downstream traffic via the AUX Antenna (or Diversity Antenna)? I have some intermittent drops in our Mobile Vehicle using IR829 servic provided by one of the main LTE carrier in LA to run a SIP Video Streaming App.. We only have one Antenna on the roof of the Vehicle now. If we purchase second Antenna, would we connect to AUX 0, and what do we need to do in configuration to the interface Cellular 0/1 (default, shut, no shut, remove?), or any changes need to be configured to main interface cellular 0/0 to get downstream traffic from both Antenna (Main 0/Aux 0)?
