It depends on your dish
If you have an "old" 18" dish, then yes
If you have a "new" 20" dish (LNB will be on a Y bracket, with space for a 2nd LNB) then you are good to go
Either way, I'm pretty sure Bell will upgrade you at no cost
A new LNB may be required, so it isn't completely ready to go if you are doing the install yourself or do not qualify for the free HD upgrade for some reason.
