I have a location that has 2 MR33 and we are looking to replace them with three MR42E.
The intent was to order 3 MR42E devices. 1 will go into main office area (direct network cable plugged into) 5-PAK Omni antenna. 1 will go in the back of the office which is closest to a warehouse building where they want to extend the signal to (Narrow Patch Antenna), and the last one would go into the warehouse building (A/C power supplied since there is currently zero internet access out there and running an aerial or underground cable is not an option for the location with Narrow Patch Antenna)
The warehouse is 200ft from back of the office where the MR42E with Narrow patch will be installed.
Would is be okay to mix the antennas or will this cause overall issues with the environment which currently has dual band steering? I attached site survey.
Since the AP's are not in the same area you may be ok but I still would be worried about devices seeing both ap and jumping back and forth and dropping. Hopefully, someone else can chime in but I think you should be good.
