I Am A Level Iii Tech, If You Have A Dish So Large And You Still Are Getting Rain Fade , Then U Have Too Many Trees Were You Live, Rain Fade, Does Have To Do With The Dish Size, But With Your Size Dish, You Shouldnt Have Rain Fade At All. So With The Dish 500 You Have To Have A Clear Line Of Sight To The Southern Skies, Or A Very High Roof, What U Are Describing To Me Is That You Have An Obstruction, That Is Messing With Your Signal, I Have In The 4 Years As A Dish Installer Rarely Found A Place Where I Couldnt Find A Line Of Sight, Regardless Of Where The Person Lives, I Have Found A Line Of Sight In The Middle Of The Woods, Thats Is A Good Tech, A Bad Tech Will Tech You, He Cant Find A Line Of Sight, Without Even Trying.
