Im planing to put the Core Module and the GPS in a enclosed housing, the problem being that they have neither GSM nor GPS connection in there.
So my first question is, for what do i need to watch out when replacing the GSM antenna. What connector does it use? Is it MHF-4 or MHF-3 or something completely different? Can i just use a generic GSM antenna from Ebay with the right connector?
And now for GPS, how do i add an external GPS antenna? Maybe de-solder the Chip-antenna and re-attach it with a coax cable in between? Or get a GPS antenna of Ebay or something?
I would really appreciate some help.
