when using outdoor IAPs for mesh, bear in mind they will be using outdoor only channels as per the regulatory domain.
On dual-radio Instant APs, the 2.4 GHz radio is always used for client traffic, while the 5 GHz radio is always used for both mesh-backhaul and client traffic.
with AP-575s (being omni directional) if you have clear line of sight, for he best throughput on the backhaul, you can easily have them around 200m apart and enable VHT80
