Digitalb reception.

My Satellite Setup
multi sat dishes pointed at various satellites
My Location
I have a no-name 1 meter solid dish with a universal lnb pointed at eutalsat for digitalb. The unusual thing about the dish is that it gets reception at a lower angle that my dishes at astra28 or hotbord or hispasat. My problem is that as soon as it rains I loose reception. :-NoooNormally the signal is approx 70% and the quality between 35 and 45%. Anybody got any ideas. Would a better LNB be the answer or perhaps a feedhorn. I live just north of Dublin and am hoping to sort this problem before the footy starts next week. Already I'm going to miss todays game because its lashing rain here today..:-doh!,.pls...any help will greatly be appreciated,.:)
