Chip:
If you want a clean canopy ejection, add an MCX connection to the cable of the antenna that will not go away with the canopy. The Core uses MCX for the GPS antenna, so you may have seen those connectors.
The OzFLARM I had a decade ago used an MCX disconnect for the remote FLARM antenna.
Have you done the same with power? PowerPoles will disconnect with a pull.
