Hi!
I am travelling to rural places often and the cell coverage is pretty bad in some of them. The plan is to connect an external antenna to both a modem used for network connection and a feature phone that I have.
However I need your help, there are no external connectors on both those devices.
Tried finding schematics of devices online to no avail.
Is it possible to find an external antenna by probing with i.e. multimeter? If you know guide for such thing online, sharing would be appreciated.
I understand a little bit of soldering will be required but I can’t even find the headers that antenna can be connected to :(
Cheers.

    Apparently some phones have these connectors that antenna can be connected to, but doing that may void your warranty.
    Also manufacturers try to hide them sometimes.

      The phones had to come with relatively big antenna because cell transmitter towers were not as common. Sometimes the distance to it was big.
      My question relates to same topic. Some cell towers on the countryside only reside in neighbouring villages or towns.
      Theoretically it ought not to be hard, just connect a bigger antenna to the device however modern devices are not designed to have external antenna.
      I hope some enthusiasts know about this stuff and help with a guide on how to find antenna connection on PCB so that external antenna can be soldered to those.
