I was thinking it might generate enough heat to keep it warm. But the comments in this thread appear to think it has a heater inside of it: https://www.youtube.com/watch?v=_JSq6xB591M
Lightbulbs are visible light and infrared. It heats the surface of your skin.
Microwaves penetrate your skin and even your skull. It's heating your brain like cooking food in a microwave. Yes, it's non-ionizing, but there's a relationship between heating, inflammation and cancer. And it's wrong to ignore it.
Just take simple precautions like not sitting right in front of a 100W space antenna, but instead mount it on your roof.
Starlink terminal transmissions are 14+GHz. It all converts to heat within a millimeter or two. It can't heat your brain. (And even if it could, "like cooking food" is a bad way to describe the fraction of a degree you'd get.)
Also the actual signal from that antenna is 20 watts or less. If it heats you, that's going to be because it's warm.
Depends on your definition of a heater, certainly there's no separate heating module but here's[0] a SpaceX team member saying it has 'self heating capabilities' in their reddit ama.
