It really depends on the dipole you are installing and the mounting orientation you are using.
But here are some options
Oberon 1021-00 with the AIR-ANT2535SDW-R will work, they also have number of other enclosures - https://oberoninc.com/
Otherwise https://www.ventevinfra.com/ has a number of options and their sales team is really helpful just tell them the AP and antenna you want to use and they will advise of a NEMA enclosure.
