Putting up a TV antenna is one of the best steps you can take toward breaking your reliance on pay TV and saving hundreds of dollars a year. Most areas of the U.S. have access to between 50 and 100 TV stations broadcast over the air for free.
As a bonus, they’ll make your big-screen TV shine. Over-the-air TV signals are typically compressed less than cable or satellite broadcasts so pictures will appear either the same quality or better.
All of the major broadcast networks now transmit in high-definition and in some areas test broadcasts for the new ATSC 3.0 standard are also underway. Those transmissions could eventually mean 4K broadcasting.
