I potentially have access to a couple of 30" dishes and if I get them, I'm thinking of installing them to eliminate rainfade and I've got the space. I heard you can actually install a dish that is TOO BIG? Because there are multiple satellites at 110, 119, etc, you can actually focus too much on one of the satellites, then lose signal strength on other satellites at the same constellation. It sounds suspicious to me, But I'd like any oppinions before I start laying cable and digging holes. Is this even possible? Thanks.
