I mean, yes, but that doesn't automatically make it safe. You know cellphone mast antennas? They also emit non-ionizing radiation yet you do NOT want to stand near one when it's working - radio burns are no joke.

I don't know if starlink has enough power to cause damage - but regardless, there's a good chance this wouldn't be legal as the device isn't certified to broadcast this way and would fall afoul of regulations.

We are talking kW output effect vs mW for a Starkink UT.

But then again: IIRC, Starlink is much more focused so power per unit square might be equivalent perhaps? It needs to get to space with a good enough SNR.

The phasing of the array might also amplify the harmful effect, I'd say. But I'm very much not an RF engineer.

[JoachimS]

The starlink antenna is not very complicated and way less focused than what a modern 4G, LTE, 5G antenna use.

As an example, the latest antennas from Ericsson supports 2000 elements, which allow very narrow beamforming and target tracking (that is phase controlled movement of main beam to track individual phones).

The starlink antenna is basically a parabolic antenna that tracks the target using motors to change the angle.

Of course, my point is just that saying "it's non-ionizing radiation" isn't a magical rule that makes it safe. You can absolutely have dangerous or even lethal levels of non ionizing radiation too. (I think I should have used a simpler example - your microwave uses non-ionizing radiation too, yet would most definitely burn you if you put your hand inside it).

[JoachimS]

The microwave is also generating many hundreds of Watts, up to kW of radio waves, a bit like the mobile base station. In slightly different frequencies. It is still several orders of magnitude less than what Starlink emits from the antenna.

There's a formula for safe distance due to the heating effects that you have to be familiar with if you want an amateur radio license. There are some funny issues there, for example certain body parts being resonant to certain frequencies.

What's the wavelength range for burning away those pesky sinus cavity infections?

radio burns are no joke.

No kidding! I'll never call in to my town's talkshow again. That DJ sucks.

Nah, unless this mod somehow boosted beyond what it transmits to the sats, it’s safe. It would require a scary sticker otherwise.
