I use bpi-r3-mini with the original case, which has 6 holes for SMA antenna connectors. Since I want to use 4 of them for MIMO antennas from the 5G/LTE module, can I safely (without damaging the board) use only two connectors for wi-fi (for example 2/5GA and 5GC antenna connector)? What’s the best way to solve this? Thank you for the tips.
