I'm thinking of ditching our cable. We have a 40" 1080i HDTV and love the high def stations, but we were considering getting a TiVO and subscribing to Netflix for $8 a month. With 2 young children and one on the way, they only watch a handful of stations anyway. I cannot justify paying 60 each month not to mention the dvr and high def fees. How do we get the local stations in high def without cable? What kind of antenna would I need, or is it even possible? I do not have an analog antenna on the roof. I have heard local high def stations are even clearer than cable, but don't know how to go about getting them. Of course I will need it by football season Help?
