Get free TV with just an antenna. Pickup major networks, local stations, and a growing number of entertainment channels. Over 100 TV channels are available near large cities, over 70 channels near mid size cities, and over 30 channels near small cities (top 200 market cities).
How It Works
A Digital Television station will transmit a 3 to 1000 kilowatt signal over the air (OTA) from a broadcast tower antenna typically mounted 300 to 2000 feet above the ground. Broadcast towers are often concentrated within a 10 mile radius near or in a city. Some towers broadcast more than one TV station, each TV station broadcast 1 to 4 or more channels. Reception range varies from about 30 miles or more for low power stations to over 80 miles for full power stations.

Picture resolution is as good as or better than cable or satellite TV. Cable and satellite operators often compress local channels before re-broadcasting. The compression reduces picture quality. Compressing signals opens up more bandwidth and allows providers to squeeze in more channels nobody watches.
Channels are in High Definition (HD) or Standard Definition (SD), and use the ATSC 1.0 protocol. Televisions that are 4k UHD can also receive Ultra High Definition broadcast using the ATSC 3.0 protocol.
Most Digital Televisions have a Digital Tuner for receiving OTA broadcast. Television's that get OTA broadcast will have a coax connector labeled "RF In" or "Antenna". Set Top Digital Tuners are available to connect to your computer / network, or monitor. Analog TV's need a Digital to Analog TV Converter to receive OTA broadcast. See Digital Television's (includes set top tuners and converters) page.
|Digital TV Channels|
The early Analog TV stations (1947 to 2009) used their FCC broadcast license RF Channel number as their station TV channel. One TV channel per RF channel. Digital broadcast can contain multiple TV channels in one RF channel and use 2 numbers for TV channel (Station channel - Sub channel), and another number for broadcast RF channel. During the transition from analog to digital most stations changed their RF channel but kept their old analog channel number as station channel.

-- Radio Frequency
Each TV station has 1 or more sub channels (e.g. 38-1, 38-2 etc.). The TV station Channel may or may not be (probably not) the same as the broadcast RF channel.
Your location and antenna are the main factors that determine the number of channels you can get. An indoor antenna will work when relatively close to a broadcast tower, within about 25 miles. Greater distances will require an attic or outside antenna.
A TV station will transmit in either the UHF or VHF frequency band. The VHF band can be sub divided into VHF-Lo and VHF-Hi TV bands. See Television Broadcast Frequencies.
RF 2 - 6
54 - 88 MHz
Most stations transmit in the UHF band, and most antenna's are designed to receive UHF signals. Many antennas are designed to get both UHF and VHF signals. In some cases a UHF antenna will receive a VHF signal at reduced power, but still strong enough for reception.
Your antenna should be pointed in the general direction of the broadcast towers, and have a relatively clear path in the towers direction. TV signals are Line-of-Sight, large obstructions (hills, building, trees) can reduce or block reception. See Signal Factors.
