We are about to install many systems in remote places in Africa and will use the GSM GX module for internet connection. Since a lot of the places will have poor connectivity, I am looking at improving the signal with an external antenna.
However, the option offered by Victron (below pic) seems quite limited. The cable is only 0.25 meter long, you need a screw base to attach it somewhere and the gain is only 3 dBi...
Does anyone have experience using antennas from other manufacturers for that?
Will 3rd party antennas work if we make sure to get one with the same type of cable, connector and frequency ranges? Is there anything else to take into account?
Thanks in advance and much sun to all!
