Yeah, great for 5G mobile but the do nothing for the wifi. Thought I'd just make that clear to save any confusion here with it being a wifi subforum.

I always caution against replace vendor antenna's...

Top vendors do have a clue about RF for the bands their devices cover, and there is the regulatory aspect as well..
