winegard Traveler slimline sat dish, how much wind?

You should worry more about the mounting and your roof than the antenna itself. When not powered on all the wind will do is push the antenna around

Three years ago we were on the desert when a fast moving thunderstorm came through. We had no chance to bring the dish down before really hard winds hit. I didn't want to try to move the dish in high winds so I left it up. We had 70mph winds and although the dish was turned by the wind, it was not damaged. We powered it up and stowed it normally. Again powered it up and it tuned perfectly and has been operating ever since.

I doubt it would take a 50 mph winds unless it's securely attached to the ground. Don't know how much weight it would take, I use a 5 gal plastic jug, weighing around 40 lbs. for my 1000.4 antenna. Possibly long stakes would accomplish a good attachment.
