Using Ubiquiti Airmax Omni 5G (AMO-5G) antennas with currently available APs?

[vinylgrrl]

Hi everyone....doing a little research for our -very- rural networking needs and hit a roadblock on this.

We currently have Airmax Omni 5G 13dBi (AMO-5G13) and Omni 5G 10dBi (AMO-5G10) antennas (tech spec sheet linked here) connected to older Unifi 5G outdoor APs (from circa 2015, technically no longer supported but antennas and APs are working just fine). We're working on upgrading our entire network infrastructure (already have a new UCG Ultra and 2 UK-Ultra/Swiss Army knife APs installed), but Ubiquiti doesn't seem to have newer versions of these antennas, which we do need for our use case (large -very- rural land parcel without cell coverage in many areas, so the wifi is for wifi calling/safety while working out in remote areas).

So my question is, could we use our existing antennas with either UK-Ultra AP units or some other type of Unifi outdoor AP? It looks like the 2.4GHz broadcast can be switched off in the UK-Ultra settings to make it a 5GHz-only AP that could be connected to either of these 5GHz antennas....is my thinking way off here?

If anyone has done this successfully or has insight on this idea, I'd appreciate your advice! The antenna connections on the new APs appear to be the same as those on the old units. so I'm reasonably certain we can connect the antennas, but not sure if they'd work properly and provide the same wifi coverage we currently have.

Are those existing APs really UniFi, or are they from the UISP (Airmax) product line?

AFAIK, the UniFi line doesn't really intend to replace every use-case that UISP supports, which is why Ubiquiti is still selling UISP products. You might need to buy some newer UISP APs instead of converting over to UniFi. Maybe those antennas will work with a UK-Ultra, but I doubt Ubiquiti considers it a supported configuration.

If you want to go with the UK-Ultra, I'd use one of the antennas that Ubiquiti specifically sells for it, perhaps this one.
