I am working on a project with AP274's and using D905 antennas. I need to mount both the AP and the antenna to an overhead surface. The bracket shipped with the D905 antenna is great for wall mount and pole mount but when you mount it horizontally overhead the only way to mount the antenna is inverted/upside down.
I have looked over the specs and antenna patterns and see no obvious problems with mounting them inverted.
What does the community think?
