Yes, both versions (Winegard aftermarket or OEM) still rotate.
But the OEM version doesn't need to be raised or lowered. Here is a photo of the OEM version.
The cable attached to the yellow connector still rotates. But being smaller, it should be less stress on it when it rotates. And if the cable gets damaged, it should be easier to replace.
That black shaft is what rotates the antenna. When installed, it goes onto a dial mechanism.
You can buy non-rotating antennas such as this one:
Robot Check
But being omni-directional, their gain will probably be less than the directional antennas like the Jack or WineGard Sensar. I had the Shakespeare version of that type antenna on my last boat... but it was not very good.
