Thank you
Had to look that one up, it said Pectinate antennae was like a comb having teeth along only one edge. Not being used to looking for that, I can't really tell when I look at my images of my moth. Guess the face shot shows it best but still can't tell only one edge. Then I found this one on bugguide that also says it is a male but it looks like teeth on both sides. https://bugguide.net/node/view/1619503/bgimage
What am I missing?

Yes
When you blow up the image above, you can see the "teeth" of his "comb" sticking out, in front of the wings.
The females of this species do not have them: ♀
Here are some other antennae forms:
Antennae with teeth on both sides are called bi-pectinate, but they are still pecinate: ♂
Yes, that's a good shot.
Also, the abdomens of this species have some slight differences. The females are very pointy at the tips and the males have two small "fins" that sick out on the sides. That usually shows up best in a top-down view. Note the shape of the shadow, in your image.

So pectinate does not just mean one sided but teeth of the comb period, I think I found some bad info with google, that makes more sense now. The end of the abdomen much more obvious, helps to see that female shot for comparison.
Sorry about the size field but note my date. With my bug photos, I have a huge backlog that need processing so they are more than a year old when I finally get them processed and identified and uploaded to my gallery, here, iNaturalist and other places. So my fingers in the shot are the best size reference you have here.
