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

I forgot a resistor on my PCB prototype – how do I add one in?

I need to add a resistor into a data line on my project. The data line is a trace and carries low speed data. A through-hole resistor will be fine. The pins for both ends of the trace are exposed, but how do I add the resistor and remove the trace?
