I search like a maniac for information about the specs of the eights antennas delivered with the BPI-R3. That forum posts had some hints but they are not quite conclusive:
Does anyone know the actual specs of the antennas and possibly know if it would be worth it upgrading to a higher tier / “prosumer” antenna?
I just made a comment on another thread, link below as I am also wondering the same as op. The ones frank listed, the link isn’t working for me to look at the details of his recommendation.
