I have seen problems with people receiving digital signals in different markets around the country. An article out of San Francisco states that something like 9.5 million households will be lost after the conversion takes place if I remember correctly. The government made a serious error in estimating the antennas that people were using. If you live in an apartment building in the outlying coverage area, you may lose reception altogether since most are using rabbit ears. They can put a better outdoor antenna on their apartment roof. People in rural areas are going to tend to lose coverage also. Even within a coverage area, it is still possible for people to lose coverage after the conversion in some markets according to transmitting maps at dtv.gov.
