If you haven’t realized, DISH DVRs have kangaroo-related names. Joeys are baby kangaroos, as such you can think of the joeys as “baby receivers” for the Hopper. They have the same interface and abilities as the main Hopper receiver, but do not provide additional network tuners. Super Joeys give you two additional network tuners. If you need to add up to 16 tuners, choose additional Super Joeys. We recommend calling or chatting with a sales agent for DISH to figure out your exact home setup.
