Hi Bill,
Here are some considerations: You will have to change the reflector, the 3 LNB's and the control box that actually controls everything. It also locates, verifies and locks onto 110 119 and 129 dish network satellites. Not real sure what the expense is. Retail on a new dish network Traveler is around 1600.00. If you like, I can do more research. The guys on the forum are perhaps more creative and resourceful.
Blessings and Joy, Fred Brooks
