I need to install a RUT240 or TRB245 in a control panel to give internet access to a HMI, at a remote location with a relatively weak 4G signal.
I will install a 4G SIM suitable for IoT application to the RUT240/TRB245 (as the SIM can automatically switch to all available signals from different carriers, so 2nd SIM is not going to be needed).
My question is for better and stable signal reception, should I use TRB245 or RUT240, although both have the same modem inside?
The RUT240 has two connectors for connecting up to two mobile antennas. The TRB245 only has one connector for mobile antenna.
Provide using the same antennas,
If I connect two antennas to RUT240, is it better than connect only one antennas to RUT240?
If I connect two antennas to RUT240, is it better than connect only one antennas to TRB245?
If I connect one antennas to RUT240, is it better than or the same as connect one antenna to TRB245?
If SIM1 slot of RUT240 is inserted with the SIM card, and I only install one antenna, do I need to connect to a specific mobile connector or both connectors are the same?
btw, there should be notes on Teltonika Manual/Introduction to identify which slot in the RUT240/TRB245 is for SIM1, and which one is for SIM2.
