The Public Broadcasting Service, or PBS, has been an American institution for more than 50 years, as fundamental to our identity as “Baseball” (a documentary by Ken Burns) and apple pie (baked in a crust that Martha Stewart calls “pate brisee”). Where else can you see high-class dramas; award-winning children’s programs, concerts, and other cultural events; in-depth news coverage; and marathon antiques appraisals all in the same spot? PBS offers all this, as well as locally produced programming that caters specifically to your regional interests.For many, PBS represents the best television has to offer, and it’s just about the only place you can see reruns of British sitcoms in perpetuity. Given the rich programming PBS provides, cord-cutters are eager to swoon over “Masterpiece” and experience “Nature” without spending money on cable. PBS has always been available for free over the air with a TV antenna, and many people still watch it that way today. For those who prefer to stream, however, it may be as frustrating as waiting for something pleasant to happen to Laura Carmichael’s character on “Downton Abbey” — although your patience may pay off in the end, just as Lady Edith’s did. How to Watch PBS Online and Over the Air Without Cable There are three ways to watch PBS shows without cable: You can subscribe to YouTube TV, the lone skinny bundle that offers PBS; use an antenna to watch it for free over-the-air; or use the PBS Video app, which is available on multiple platforms. YouTube TV Of all the skinny-bundle services available, YouTube TV is your one and only option for watching PBS without cable. YouTube TV apps are available on multiple platforms, and the service has a free trial if you want to give it a whirl before committing any cash. Free Over-the-Air TV If you’re looking to watch PBS for free, an over-the-air antenna may be your best option. If you want to receive PBS and other broadcast channels over the air, there are many TV antenna options available. You just have to consider your distance from the local PBS transmitter, the direction of the transmitter, and the obstacles that may sit between your home and the transmitter. PBS Video PBS has a digital streaming app called PBS Video that provides video on demand on your TV, phone, or tablet. It’ll let you stream some on-demand programming at no cost, although you can increase the amount of content you get by paying for a premium tier called PBS Passport.
