Issue: I need to run the two external antennas outside of the room where the RPi/RAK2013 is located. I have already tried; I ran just one antenna cable and put the antenna outside of the room. The other antenna is still directly connected to the case. When I turned the Pi on, the modem was rebooting and non-responsive. I need to know how to run antenna cables in the proper way to get signal from outside of the room.
Setup: RPi Model 3 B+, RAK2013 connected to Pi via UART, powered from UART.
One end of cable with SMA connector, connects to RAK2013 case, other end has SMA connector, runs outside of room and connects to LTE antenna.
Antenna 2: Unchanged, connected directly to RAK2013/RPi case.
RAK2013 becomes unresponsive, reboots, when one antenna is ran to a distance outside of room.
The cable I’m using is LMR240. The run is about ~10 feet. (~3 meters).
Please let me know what to do here to get it working properly. Thanks for your help.
