Hi Jan,

Really cool demo, and it has so many uses, being able to have multiple nodes all talking to the receiver unit. I bet it was an awesome feeling when everything worked across all protocols to make the first SMS get received! : )

I got a set of antennas from Project14 <3.

Here's the reported connection strenght for a GSM connection from Arduino MKR GSM 1400 and my operator:

Here are some signal strenghty comparisons - all on a scale from 0 no reception to 31 best reception:

Without antenna (don't do this at home - bad behaviour): 1
With Molex 146185 Cellular Band antenna; 22
With Molex 105263 Cellular 6 Band antenna: 23
With Molex 146220 GPS + WIFI combo 23
With Molex 146186 GPS + WIFI combo 14

Very good project showing LoRa combined with SMS. Thanks [mention:acaf6a9338de4eef8f6717d5561ed01d:e9ed411860ed4f2ba0265705b8793d05] for the video.

I've added a video showing the project in action
