I have PoE Gigabit switches, so the biggest concern are the mounting options. I am right now leaning towards the U6-Mesh, which is said to be ok with tabletop placement (https://ca.store.ui.com/ca/en/products/u6-mesh), but on the other hand the radiation pattern does look weaker than the U6 Pro’s https://help.ui.com/hc/en-us/articles/115005212927-UniFi-UAP-Antenna-Radiation-Patterns

Exactly my thoughts. I want to keep my current router + gigabit/poe switches. I am just struggling with finding a good access point for my limited mount options.
