hi guys i am currently using a 1.1 triax i am situated south coast ukand my 1.1 triax is on the roof 4 floors up.My problem is when the winds come the dish tends to come off the arc not a real problem for 13 16 19 east,but a no go for 30 and 15 west.I have been thinking of downsizing my dish as was wondering what size I could go down to without losing a noticiable signal level.\the other thing i have noticed is the nuts and bolts that came with the dish dont seem that sturdy as they were a few years ago,is this a general thing or do some dish manufacturers produce better quality,if anyone could point me in the right direction maybe to better dish more resistant to wind iI would as always be most grateful
