I know there is "External Antenna Site Preparation and Installation" document on extranet which covers all external antenna radiation patterns and installation notes. But I can't seem to find any document about internal antenna models.
So does these models radiate like spheres or like donut shape like external omni antennas? What is the best method to install them? Ceilings or brick wall mount? most of our 3610 and 3825 models are mounted to walls becouse it was easy to mount but I wonder if we could get better coverage if we mount them to ceilings.
