this is what i wanna do......
let me know if this is the right procedure
i have dtv dish on the roof with only one cable coming out of dish
i will have to repoint dtv to 119w and change it in my menu of the fortec so i can find out what signal i am getting once that is done i can load the bin for it and presto i am getting dishnet ......
let me know if this is good :)

sounds good as long as you are pointing at 119 it should work fine.

Dtv dish pointing same way just turn right or left to catch dishnet
