I think it's because the P3S antenna is a different design from the others'. It's not a P3 4k/Pro antenna, just a single one. The design is different, and it's actually shorter than other antennas in the P3 range.
I chose this design precisely because I knew it was smaller. If it turns out to be too small, I'll try another design. But I know that a design that is for other drones in the P3 range will be too big for a P3S controller.
Sorry, but I don't think you understand what you're saying.
TTT's video was posted before the P3S was released by DJI and also before the P3 4K was released by DJI. So your comment doesn't make any sense.
But that's okay, because the deflector, at least Erskine's deflector, will work for 5.8 as well as 2.4 without having to move the focal point. I confirmed this a couple years ago when I was in emails with Mike Erskine. Whether TTT's dumbed down version would work, I think it would. But that doesn't change the fact that it is definitely a dumbed down version. You will be sacrificing signal strength using TTT's template. That might be okay if you had no choice and you were using a dual antenna controller, but you're not. And since you're not, it doesn't make any sense to use the smaller deflector. TTT's template is for a dual antenna controller. It is not for a single stick antenna controller.
If you see Erskine's comment, he writes: If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain.
But you're not choosing either of his suggested options. You're going the other way and making it smaller, and you're doing it without reason.
But hey, it's your system. You can do anything you want.
Good luck
