Found the perfect rooftop antenna

Now that I'm convinced that I'll probably never go back to subscription, I'm considering buying a DVR with a digital tuner. I just finished hooking up the new Winegard antenna that my neighbors purchased from Costco and it works great. The problem with my old fashioned rooftop antenna is that it does get certain channels because it isn't compatible with the frequency being used by them. Also, the signal strength is week on my 40+ year old antenna compared the Costco antenna. Unfortunately my TV doesn't have a digital tuner, so I still would need to buy one of those. It would be nice if I had a DVR for recording programs, but I would also like something that is going to benefit my big screen TV in the area of 1080i screen resolution. The digital converter I was using only provided 480.
