Mounting a Mic Flag on a Boom Arm???


Hey there, I apologize for this question which is probably stupid but I've crossed a problem that I can't seem to solve with Google-fu. I have the Blue Yeticaster. (Blue Yeti mic, Ra dius shock mount, and Compass boom arm.)

I intend to replace the Yeti and Radius with an XLR mic down the road but that isn't what I'm here for.

I want to find a way to mount one of those box mic flags between the Compass and the shock mount in a way that would work now or when I upgrade since I intend to use the Comp ass either way. The way you see them do it in radio studios and what not. The boom arm isn't long enough to do it out of box.

Is there an extension I can buy to put between the two? What would it be called?

Hope I'm not being to vague or confusing.

Thanks in advance!
