Julie and Anthony Bayerl of St. Paul, Minn., love watching prime-time shows on the sleek 50-inch television in their bedroom. They also love that they pay nothing for the programming.

The only thing they do not love is how a low-flying plane, heavy rain or just a little too much movement in the room can wipe out the picture.

“If someone is changing in there, it messes up your reception,” said Julie Bayerl, a legislative assistant. “We try to stay very still when we watch television.”

The Bayerls are using an old technology that some people are giving a second chance. They pull free TV signals out of the air with the modern equivalent of the classic rabbit-ear antenna.

Some viewers who have decided that they are no longer willing or able to pay for cable or satellite service, including younger ones, are buying antennas and tuning in to a surprising number of free broadcast channels. These often become part of a video diet that includes the fast-growing menu of options available online.

The antenna reception has also led many of these converts to discover — or rediscover — the frustration of weak and spotty signals. But its fans argue that it is tough to beat the price.

“My husband’s best friend thinks we’re big dorks for having rabbit ears and not cable,” Julie Bayerl said. But when their introductory price for cable TV and Internet access expired this year and the bill soared to $150, the couple halved it by cutting TV. “It wasn’t something we were willing to pay for,” she said.

Many pay-TV customers are making the same decision. From April to September, cable and satellite companies had a net loss of about 330,000 customers. Craig Moffett, a longtime cable analyst with Sanford C. Bernstein, said the consensus of the industry executives he had talked to was that most of these cord-cutters were turning to over-the-air TV.

“It looks like they’re leaving for the antenna,” he said.

Last month, Time Warner Cable fought back with a lower-cost package that it said might appeal to people who are feeling the economic squeeze. For $40 in New York, or $30 in Ohio, customers can get a slimmed-down set of channels.

To be sure, around 90 percent of American households still pay for cable or satellite television — a figure that in recent years has been slowly and steadily rising. But Americans’ relationship with television has recently been in flux, in part because of the switch in June to digital broadcast signals.

That initially gave pay TV providers a group of new subscribers who had worried that their old sets would not pick up the new signals. But analysts say some of those subscribers have since gone back to free signals.

Another big change is the rise of Internet video, which can ease the pain of losing favorite cable channels.

Bradley Lautenback, 28, who recently moved to Los Angeles to work at Disney, found enough alternatives to allow him to turn back the technological clock on his TV.

“I’ve always had cable. It’s the thing you do when you move to a new place: call the company and set it up,” he said. Not this time. Instead, he got an antenna and now watches over-the-air news and sports, complemented by episodes of shows like “Entourage” that he buys from iTunes. “I don’t miss cable at all,” he said.
