What about heavy downpours? When its raining cats and dogs my sat tv goes out. That would not be cool for an internet link.
I’m not a physicist but I’d guess this system is a little more resistant to weather.
Directv is a directional signal. The satellite is in geostationary orbit so it stays in the same spot in the sky at all times and your dish has to be aligned perfectly on it. Geostationary orbit something like 20k miles distant, which is why it has such crap latency for internet and is easily interrupted.
Starlink is Omni directional. It has to be because the satellites are not geostationary. They’re very low altitude, something like 600 miles for the highest orbiting shell. The lower ones are 400 miles maybe? Anyway, the signals for this system are Omni directional, more like cellular towers. The much shorter distance and Omni directional nature likely means it will tolerate weather better.
That’s just my semi educated guess.
Part of that, I’m sure is that your small parabolic dish is literally filling with water (or snow). I’m guessing that the antenna for the Starlink satellite signal will not be parabolic, but rather something more akin to a digit broadcast antenna. Plus, as others have pointed out, these are really low altitude satellites — not the distant geostationary variety with their directional signals.
last night it was raining hard here in Orange county ca, and i didn’t have any problems with directv at all
