...I still dont know why you have so many issues with rain fade...
I read a lot of people who say similar things, and I don't know why you (and they) are not having rain fade issues.
Here in central Okla, everyone I know that has either pizza service complains about it. I have Dish... Bro-in-law a few hundred feet down the road has Direc... and we both see it. My Dad a mile away has Dish and he sees it. Several of my employees have one of these services, and they see it. Same with the folks I go to church with.
Out of all these people, I'm the only one who actually installed his own equipment. But surely the local install guys don't mis-align all the dishes they install. I know for sure that my dish is pretty well peaked.
Keep in mind, we don't lose service just because it rains. But we get some real doosies through here, and we lose service every time.
I can't explain why some don't see rain fade as a problem. But you can be rest assured that most of them don't live in central Oklahoma.
Cheers
