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.
Antenna 1:
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.
