Hi,  
We are using MC7304 module for GSM & GPS in our project. I have doubt in choosing antenna for it.

MC7304 has three Antenna connectors Main RF Connector,GNSS Connector,Diversity/MIMO  
Do we need to use All these 3 antenna?  
Will this modem Support internal Antenna?

Thanks,  
Sathish

Module did not have internal Antenna.  
for data connection, you need connect Main RF. If you need more throughput for downlink, you can connect Main RF and Diversity/MIMO.  
Diversity/MIMO just for download link.

For GPS or GNSS, you need connect GNSS Connector

Thanks  
Suggest me some antenna types for each Main RF,GNSS and Diversity/MIMO which will be more efficient.  
Also where can we buy them.
