One: you will not get 40.5 with the others that you want to get due to deg spacing. More importantly, you won't get this sat cause its all cband.
Two: You shouldn't have a restriction on # of dishes if its installed in your own "exlusive" living area.
Three: Dish is made for about 4 deg spacing, although some users here have gotten 2 deg.
Four: Satmex 5 and 6 are mainly Cband, which you can not get with this dish. What channels were you looking to get?
Five: What do you intend to get with 110 and 119?
