DIGITAL CHANNEL is the actual VHF or UHF channel number used to transmit digital TV signals.

CALL LETTERS are the official call letters issued by the Federal Communications Commission or other authority.

NETWORK refers to any major network affiliations. 
Abbreviation IND indicates that station is Independent, and not affiliated with any major networks.

COMMUNITY is the city of license or community served.
Actual transmitter location is listed in  (  )  if different from Community.

Transmitter coordinates:   LATITUDE is listed in degrees, minutes and seconds NORTH.
                                   LONGITUDE is listed in degrees, minutes and seconds WEST.

RANGE is the estimated distance in Miles from the transmitter, that the FCC expects to be interference-free from other
stations under normal circumstances.  Transmit antennas are Omnidirectional, unless indicated by D for Directional.
Coverage maps can be found on the Federal Communications Commission website at www.fcc.gov
Such coverage areas assume line-of-sight between the transmitter and an outdoor receive location,
at nominal rooftop level from a single story building.  Actual distance can be much further, especially in elevated
receive locations, or when using extremely efficient antenna systems.  Reception will vary dramatically by location,
and placement of antenna, so these numbers should be used only as a rough guide of expected coverage.
When in doubt, contact a professional antenna installer, or the engineering department of your local station.

DIGITAL SUBCHANNELS are the TV channels carried within the television signal's main carrier.
Up to 6 standard definition television signals may typically be placed within a digital television carrier.
Some stations are even transmitting radio signals, which take even less bandwidth and can be greater in number.
High Definition signals are indicated by  "hd" suffix.  When HD is transmitted, there are normally no more than two
additional standard definition signals.  Some stations may transmit more signals, but at the risk of degrading the
picture quality of all signals due to going beyond the guidelines of good engineering practices.

DIGITAL TV and HDTV (High Definition TV) should not be confused.
Digital television is the latest television industry standard for the broadcast of video and audio using digital signals,
and provides superior picture and audio quality when compared to previous analog transmission format.
High Definition (HDTV) signals are a form of digital television.  You do not need an HD converter or HD television set to
receive digital TV.  In fact, channels transmitting in High Definition can be received in Standard Definition with basic
non-HD digital TV converters or digital television sets.
