I may need to install a Meraki MR-18 Vertically, I normally mount horizontally so have a good idea of coverage but don't know what the coverage will be like when mounted vertically. I looked at DataSheet but don't understand what the chart means.
Could someone explain what is means. I see little numbers, -5 , 0 and 5 within the chart and on the outside of the chart I see various number, 0,330, etc what do those indicate? The place I am installing it a courtyard which very little interference or anything which would block signal. Thanks in advance for your help. Please see attached.
