An "old old" DirecTV dish WILL work....if it is one of the "Hughes Network" "D" Style dishes and some older origional "Dish" dishes had that setup..... probably 4-6 years old....it is not square and can point to the 61.5 location....
There is....or was.... a "square" converter to a "D" style adaptor to convert from a square end dish to a Dual 300 (current D style (single satellite) LNB)...but I haven't seen one in awhile....May want to contact a reputable retailer.
You can just point to the 61.5 with a "legacy" (non DP LNB) direct, but you won't get anything else....and you could use an old "SW64" switch, lots more cables, a second Dish 500 antenna, optional SW21 switches, etc, with the legacy LNB's....blah blah blah....
There are a lot of Sky Angel broadcast setups still using this equipment.
