I have a task to cover some area near the building, there is no masts\poles there, so you can place ap only on building itself, i want to use 1522 AP, because it's suitable for out environment (we can have temps lower then -20C so 1242 is not an option), but i couldn't find proper patch antennas for 1520 series, cisco specifies only omin ones.
So, can I use 2.4 patch antenna, replacing -RP-TNC connector with -N one?
It's not possible to mount ap indoor and place antenna outside.
If it's not possible - what thermoboxes can you advice for 1240 series?
Other companies make RP-TNC / N adapters, or you can use the boxes listed below with a 1242.
If you choose to adapt the antennas, be sure that doing so will keep you within the radio licensing/usage specifications in your country.
