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?
  • An RF circulator that only allows signals to pass one direction in and out the 3 ports.
  • A SPDT RF switch that takes a couple of logic inputs and selects between two RF output paths
  • A two-way power divider to connect two antennas simultaneously

Are SMT components bad for high voltage applications?

Many assembly factories are asking for SMT jobs, while I think through hole would be a better option for a high voltage application. Before the high voltage project is started, we need to make a call on SMT or Through hole parts. Is there a study on this?
