How do I use two antennas with a single Bluetooth module? (BLE repeater)

I am working on a project that uses small Bluetooth low energy (BLE) beacons to track important items. Is there a way to connect two antennas to a single BLE module that could either listen/broadcast on both antennas or multiplex between the two? Or any other idea?

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable.
