Hi All.

My want to add GSM Internal and external Antenna switching in my project. I'll use GSM Module with Antenova A10340 Internal Chip Antenna and External SMA Antenna connector. I want to implement a circuit so user can choose either internal or external antenna option.

Can anyone advise how to achieve that?

Thanks in advance.

Regards.
