Did you know that people in or near big cities can receive the major network channels (ABC, CBS, NBC, FOX, CW), plus PBS and local stations in Hi-Def for free? It’s called broadcast digital TV. I was able to get thirty channels total in Providence, RI and over 100 in Los Angeles, CA. It takes a little leg work to set it up, but I’ll guide you through it.
As part of this switch over, we installed an over-the-air antenna. This allows us to pick up a large number of local channels. We live close enough to the Des Moines metro area that we can pick up strong signals from a lot of stations in Des Moines. (It’s worth noting that this is aided by the fact that there’s a repeater tower within five miles of our house, which means the signals are strong.) This includes the major broadcast networks – ABC, CBS, Fox, NBC, PBS – and a large number of additional channels of varying quality, including an all-children’s channel and a channel that seems to be nothing but a loop of the weather forecast.
The question of "when does it make sense?" can easily be rephrased as "how much money can I save?" and one of the biggest factors will be the price difference between combined internet and TV service or just internet. These are also the options that vary the most widely based on where you live, and the availability of promotions or contracts that can keep prices down for a short time.
