In this questionquestion and answeranswer pair I see that the ISS can maintain data links to earth through direct access to ground stations as well as through the TDRSS geostationary satellite network.

What kind of antennae are used on the ISS for these links? Are they directional? Do they have to continuously move to maintain a live link - for example in the case of the live streaming HDEV views? I'm wondering if they are phased arrays which can be steered (potentially very quickly) electronically, or a more conventional gimbaled dish, a little like the picture below.

I got excited when I found this image through a google search for space antenna GIFs, but it turns out to be something completely differentsomething completely different. (also here)

Do the antennae on the ISS have to constantly move to maintain data links?
