Antenna holder for the mount for the Ubiquiti Unifi UAP-AC-M Mesh AP. This holds the included antennas at the recommended 45º angle, and should help prevent weather, birds, etc. from knocking them out of position.
The holes are ellipses, and not circular. This allows the holder to be tighter fitting once it is slipped all the way over the antennas and they are tilted into position. You will only be able to slide this over the antennas if they are properly oriented before doing so.
Print with support to get the short gap at the bottom between the holes to not droop too much. The 45º portions won't need any support. Infill percentage can be very low (20%), and barely needed at all.
