A:Answer The coax which delivered the cable TV signals is not suitable for the antenna. A coax directly from the antenna to the TV will work. The coax will decrease the signal, so depending on the length of the coax and the strength of the over-the-air signals in your location, you may need to add an amplifier. If so, the Winegard LNA-100 is one of the best choices. If you watch movies, the Internet is a source for both free and paid movies and news.
