The CubePro 60’s are meant to be PtP, not PtMP. You would need the master 60Ghz antenna to be the Sector version, or the wAP 60G AP [older model] to be the sector.
I do not believe MikroTik has released their radiation pattern for 60Ghz products. They are keeping the 60Ghz info close, essentially proprietary to them. The same with a few other manufactures.
