Huh, my observations have been different. I lose TV even before the rain and wind starts (trees make any wind quite visible), just because the dense dark rain clouds are blocking the signal path. The rain typically starts a couple minutes later.
For digital TV there's an incentive to maximize bandwidth. So they're going to trade off signal:noise to get 99.99% (1-10 minutes/mo), but not 99.99999%. Especially since as you say, the wind will result in some signal interruptions anyway!
- Moru 9y agoYou might not have the most optimal angle on your satellite antenna so it's very sensitive.

- ficklepickle 9y agoYes, very likely. I used to install and service satellite TV systems. You probably have low signal strength to begin with. If not, perhaps there is a tree that only blocks the signal when it's windy. I once had a customer that lost signal in the rain. After much investigation, I found a splice in the cable...in the gutters, which filled with water when it rained.

I should have said it's entirely possible to make Ku withstand the worst weather conditions known to mankind, which is not the case for Ka. Trivia: Ku stands for K-under, and Ka stands for K-above, where K-band is IIRC something between 18-27 GHz. Electromagnetic transmissions in this spectrum are absorbed by water vapour, so it's a very bad idea to use this spectrum for satellite. Again IIRC, above 70Ghz, the atmosphere stops being radio-transparent. Ka is way more efficient, but you need a ground station, a satellite and modems that are built from ground up to cope with rainfade. The tricks that work with Ku won't work with Ka.
