I was wondering what kind of modifications I need to make to use an external antenna with the Things Uno.
I'd like to try to put an external antenna on this board, specifically this one
(which I'm using with an RFM95 already)
So I've soldered on an SMA connector already.
I guess I need to either bridge the antenna trace to the connector center pin, or bridge it with an SMD capacitor like 10 pF. The on-board chip antenna is currently still connected to the trace.
Do I need to cut the trace to the chip antenna?
Or can I just leave it on (so it sits parallel to the external antenna)?
Is there a recommended procedure for using an external antenna?
