I am a retired person on a fixed income and totally confused about all the changes taking place in HDTV. My house has a satellite dish which has been on the roof since I moved in 5 years ago. I have been receiving local TV via rabbit ears, and I am not interested in premium services. I now see that there is something called Free to Air which allows individuals to buy a receiver and get over the air local programs without signing up for a service which I simply can't afford. I don't want to break laws or do something I shouldn't. Can someone help me through this maze of information, and If I am able to do this, what economical receiver / supplier would you recommend?
