Groove 52ac - No MIMO?

RouterOS Wireless Networking
1

I am looking at using the Groove 52ac WiFi radio in an automotive application for uploading dash cam video to a storage server located in a garage. When the car parks in or near the garage, the Groove will automatically connect to the router and start pushing up video files. But to get the best throughput using 802.11ac, I thought at least 2 antennas were required, preferably more. This radio only has a single antenna connection. With only one antenna, will the performance be any better than a regular Groove 52n radio connecting to an 802.11n router?

Thanks.

There is more to it. Yes, there is only one antenna, but 802.11ac supports higher data rate (MCS9 vs MCS7) and wider channel width (80MHz vs 40MHz).
These details are in the PDF files:

So with this info known, we can look in the MCS index table here:

What we will see is:

Groove 52   = MCS7 1x1 at 40MHz = 150Mbit data rate. 
Groove 52ac = MCS9 1x1 at 80MHz = 433.3Mbit data rate.

Also the Groove52ac has a Gigabit port, to allow the higher speed. Groove 52 only has a 10/100Mbit port.

Thanks for the follow-up info, much appreciated.
