in heavy rain, like thunderstorms, will almost always be total loss of signal, typically as the storms are approaching, because the dish is usually looking thru more of the rain than when it is directly overhead. Also keep in mind there are fades in the uplink direction wherever the uplink transmitter is located as well (say Toronto)??
Moderate rainfall shouldn't cause ya to lose completely unless something is wrong.
60E is kinda small. Ya might have better results with a 75E or next one bigger than that. probly depends where u are located.
