How to Find Free Local HD Channels
Most 4k TVs and HDTVs have a built-in digital tuner that can scan an antenna connection for available signals from local broadcast stations. Depending on weather and other obstacles, channel strength can be inconsistent. But usually channels with nearby broadcast facilities, if unimpeded, are near perfect and can look and sound even better than cable or satellite!
To find local channels simply connect an outdoor or indoor antenna (here are some affordable options from Amazon) to the TV input of your TV, or, to a device like an inexpensive DTV box or Amazon Recast box connected to the TV. Be sure to select the TV or Antenna source (most TVs have multiple input sources such as HDMI1, HDMI2, USB, etc.). Use the channel button for your TV to search through channels manually, or, do an automatic channel search that will store all available channels over-the-air.
You can also use the websites AntennaWeb.org or DTV.gov to final local broadcast stations by entering your zip code. The results will give you directions on which way to face your antenna to maximize the signal reception of a specific channel or network.
The local HD channels traveling through digital signals in your area should also be available from your service provider, but are also free over-the-air if you choose to bypass a paid service (also know as “cord-cutting.”
Why Are Local TV Channels Free?
HD channels, along with SD (standard-definition) channels, are available as a public service from broadcast stations across the country. After the analog-to-digital conversion that took place in June, 2009 digital signals (which take up less bandwidth than analog) are traveling in all directions. To receive digital High-Definition or Standard-Definition channels all you need is a digital television or digital receiver and CEA-certified antenna.
If you have an older tube TV that isn’t HD or Ultra HD you can still get standard-definition channels in digital quality using an analog-to-digital converter box that sells for about $25 or higher.
