Hello @BrentG I'm not in the Meraki Support organization so while this isn't an official statement that it's supported, I don't see any issues with your plan. They are pretty much the same dual-band antenna elements with the same 4/7 dBi gain and roughly the same omni coverage pattern. Plus the ANT-20 Meraki omnis are not smart antennas like the indoor models and do not self-identify to the AP. So while it's not officially supported because the Meraki APs are only tested with the Meraki antennas (one exception being the stadium antenna), I wouldn't expect an issue doing this. Using Meraki ANT-20 is what has been tested and fully supported and guaranteed to work, but the 2547V-N will likely work just fine, but do test and confirm of course.
