Meraki's has nice diagrams showing Vertical and Horizontal RF patterns for all MR radios. Does anyone know if these were generated without metal mounting plate attached? They seem a little too symmetrical considering the attenuation from the metal mounting plate.
This is a good question @scrapiron, I would imagine that the RF measurements and diagraming do take into account the mounting plate. Without working at it a bit, an MR would be challenging to mount on a ceiling or a wall without the mounting plate. Not to mention it could be a safety concern, ie an AP falling. 5 GHz as we know would be more impacted / not impacted by a mounting plate, if you take a peek at the attached, it appears the mounting plate is considered.
