what do you call this signal?

Is that Norm Drucker? Early NBA refs had personalities: Sid Borgia, Joe Gushue, Mendy Rudolph, Earl Strom, Richie Powers. I've always thought it regrettable that we've been trained to restrain ourselves in the interest of "uniformity."

I agree. They all seem bald or short hair, often slicked, with little body fat. The quality seems pretty good actually but I'd like a little more personality. I recognize a few of the under 40's but most of them are just blending together and I can't tell them apart.

Yes, it is. There's a link on his Wikipedia page to a photo of him wearing number 7 (you can see that in the above video) with Wilt and some others in the photo.
