I want to use an Arduino MKR GSM 1400 in my area wich has a bad connectivity on mobile internet. On my phone it's very weak and if i drive to the next village it works sometimes on the arduino with the given standard antenna but I want it to work in a wider range. Is there any antenna available specifically for mobile connections wich you can put on a arduino? And how do you call them and where can I buy such a thing or even build it myself? Do you have any suggestions for such an antenna? And is there something I can improve with just using software to strengthen the signal?


On one end of the MKR GSM 1400 is a U.FL antenna connector. To that you need to connect a U.FL To Female SMA Adaptor. That adaptor can then screw into an SMA GSM Antenna of your choice.

  • I get the adaptors from eBay. I can't recommend a specific antenna, but the ones with a long cable and a magnetic mount (that are intended to go on top of cars, etc) would allow you to place the antenna in a high location where you can get better signal. – Majenko Sep 1 '18 at 9:17
  • @The_javascript_King The connector is one thing, but antenna performance is dependent on antenna type and gain. Try to compare gain values (in dBi) of the antennas you're buying -- the higher, the better. – Maximilian Gerhardt Sep 1 '18 at 11:05
