The antennas that were designed in the olden times were not equipped to receive new channels that are now used for digital TV, especially, 10, 7 and 9. Only if robust and high-quality signals are received, it may be possible for the Digital TV to work. It is important to note that old TV antennas will come with old splitters, cables, and connections that will not work well for Digital TV reception. It is better if you get your entire system checked by a professional to enjoy hassle-free Digital TV Viewing. In the case of a poor analogy picture, the Digital TV may not work well with the existing equipment.
