Hi, I just switched to Dish after Comcast and I have a premiere. I want to use my premiere to record some great channels that Dish does not have, like MEtv and hd network. If I record all my network programs on my tivo that leaves more room on my hopper for cable recordings. Anyways, do i need a special antenna to get the ota channels on my premiere ? If yes, I would appreciate any recommendations for least expensive. TIA !
