5GHz UNNI Channel Support
In Roku OS version 12.0 DFS channel support was added for those models equipped with Realtek 13xx chips. Per the Wikipedia Chart at https://en.wikipedia.org/wiki/Roku#Feature_comparison, those models are:
• Streaming Stick 4K/4k+ (3820/3821)
• Express 4K/4k+ (3940/3941)
• Ultra/Ultra LT (4800/4801)If you have a 4800 model series Ultra, you should be DFS compatible.
From Roku support article https://support.roku.com/article/21332729601687, the DFS "excluded" (non-supported) list comprise the following...
The following streaming device models do not support DFS channels: 3600X, 3800X, 3810X, 3811X, 4200X, 4201X, 4205X, 4210X, 4210X2, 4230X, 4230X, 4230X2, 4620X, 4630X, 4640X, 4660X, 4660X2, 4670R, 6301X, 6302X, 6303X, 6102X, 6103X, 6104X, 6106X, 6107X, 6108X, 6109X, 6110X, 6112X, 6113X, 6114X, 6402X, 6403X, 6404X, 6405X, 6406X, 6407X, 6408X, 6409X, 9101X
----
I was able to previously test my RokuTV, my Streambar 9102, and Express 4k+ 3941 and they all worked on DFS as indicated. My Ultra 4660 is not supported and thus was not able to use DFS.
I do not personally use DFS, but for those that can get some benefit from DFS, good to see Roku starting to offer support/compatibility.
