I am building an open-source NB-IoT tracker from a GitHub repository. Should I use the rigid PCB or the flexible FPC version?\u003c\/summary\u003e\n\u003cp\u003eIt depends purely on your 3D-printed enclosure. If your enclosure has flat inner walls and dedicated mounting slots, use the rigid \u003cstrong\u003e3508\u003c\/strong\u003e or \u003cstrong\u003eD41\u003c\/strong\u003e for maximum 3.0dBi gain. If your device is curved, extremely thin, or oddly shaped, the \u003cstrong\u003eTXGN-PCB-6508\u003c\/strong\u003e flexible antenna is the best choice, as it can be peeled and stuck directly to the inner curved plastic.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"faq-item\"\u003e\n\u003csummary\u003e3.
