FYI, there is now a 9166D model with an internal directional antenna:

I am a little disappointed that it’s not higher capacity, such as a theoretical 9136D, but depending on your client counts and throughput needs, it could work well for you so you have an all 6GHz design. Like the 9130, it can run in dual 4x4 5GHz mode (via the XOR 6 GHZ radio), you just won’t get the 6 GHz fourth radio of a 9136(i).
Otherwise, I’ve always been advised to keep generations of access points the same throughout the building or area (especially when frequently roaming between them). On the other hand, if you use the ANT9103 with the 9130E now, you should be able to just swap the AP later once a 6 GHz external antenna AP is released (pending FCC regulation) and keep the antenna since it is 6 GHz capable. But by that time, who knows, there might be another new model to replace the 9166. I don’t know if there’s a clear best solution to this but am interested in what others say.
