How to use two antennas with a single Bluetooth module? (BLE repeater)
I managed to find a couple of RF experts at my company and they recommended looking into 3 options:

-A two-way power divider to connect two antennas simultaneously

-A SPDT RF switch which takes a couple logic inputs and selects between two RF output paths

-An RF circulator which only allows signals to pass one direction in and out the 3 ports.

After looking at each solution I've decided to try a prototype with a surface mount SPDT switch since they can be found for a few dollars and fit on a small PCB.
