I am using a Positioning module that has a SMA port to hot plug an SMA antenna. It also has pins available through its foot print to connect a GPS Antenna.
The module name is [SIM908] [1]. I was not able to spot a place in its data sheet that describes if both antennas can be connected at once.
I want to solder a passive chip antenna about 5-10cm away from the GPS module to be used in case should the external SMA antenna is broken or disconnected. At least with a longer fix time, I would still have some fix, without having no fix at all.
Would having two antennas connected, one through PCB trace and other through direct SMA cable be a problem for the performance of the device?
