Getting the most from America's New High-Definition Television System is simple and inexpensive. You just need an antenna for sets made after 2007, and a Converter Box if you have an older TV. No need to get cable, satellite or a new TV to enjoy America's DTV Channels.

"Multicasting" allows stations to broadcast up to six new channels in the space of their old one. Channel 9, for instance, is now DTV channel 9.1, 9.2, 9.3, etc. Cable and satellite would have you believe they carry most of these new channels, but they don't...

Cable and satellite strip and leave out most broadcast channels to save space for other $ervice$. To get genuine HDTV just add an antenna and converter to your existing setup. You'll be amazed how many HDTV channels you can tune, and how much better everything looks over-the-air!

All of these new channels, and many more, are Free! No cable or satellite is needed for any of them. Just select an Antenna, using the information below, to receive crystal clear HDTV signals Free in the Columbia, Florence and Myrtle Beach Areas.

Antenna Selection Guide

To find the perfect antenna, first list the RF Channels in Columbia, Sumter, Florence or Myrtle Beach which you want to watch. The CEA, Consumer Electronics Association, and NAB, National Association of Broadcasters, created the AntennaWeb to help you with the rest. Free! An example of how it works is presented below.

NOTE that all TV stations are transmitting on different channels now. To avoid confusion, however, the new tuners and converter boxes allow a station to keep its old channel number while automatically switching you to its new RF Channel. Some of the new RF Channels are VHF but most are UHF.

RF Channels on your list numbered less than 14 are VHF. They need a broader antenna than UHF channels; the ones numbered 14 and up. Since HDTV is 91% UHF, you probably won't need to use a broad antenna.

Most need an Indoor Antenna. They work just fine with older TVs using a converter box, and with all new TVs. You'll need to use an Outdoor Antenna if you're more than 15 miles from stations' towers, but most towers are clustered near town and are very powerful.

A Station Tower Map will appear beside a list, as shown below. The strongest stations are at the top. Record the RF channels, and Antenna Color Codes, of the stations you want to watch. You'll need that information to select the proper Antenna.

What's important is to get-a-feel for the distances and directions to desirable stations' towers (under "Dist" and "Azimuth" above). Let's select CBS, ABC, FOX, NBC and PBS Networks, all of which are farther than 15 miles away. We'll need to use an Outdoor Antenna to receive them. Fortunately, station towers are clustered in most cities - East of us in our example.

Antenna Color Codes

Color Codes represent an antenna's reception strength. Within 15 miles of stations an Indoor Antenna can be used (in the Yellow, Green and Light Green Zones). Farther away you'll need to use an Outdoor Antenna. Our Example calls for color codes blue and violet. The stronger violet type will work for both. Since four of our desirable stations' RF channels are VHF (all but ABC are less than 14), we'll need a broad UHF/VHF antenna.

HDTV Antenna Color Codes
 Small Multi-Directional Antennas
Small Multi-Directional HDTV Antennas
DESCRIPTION   The smallest of TV antennas receive UHF and VHF RF Channels from all directions.
APPEARANCE   Good looking home interior designs.
USE   For use where signal strength is high and with No pre-amplifier.
 Medium Multi-Directional Antennas
Medium Multi-Directional HDTV Antennas
DESCRIPTION Larger and slightly more powerful, may be placed in interior attic.
APPEARANCE These antennas include novel stick, wing shaped or disk antennas.
USE An amplifier is recommended for 20 feet long, or more, cables from the antenna, or when more than one TV or VCR is used by a single antenna located AWAY from reflecting structures or in valleys.
 Large Multi-Directional Antennas
Large Multi-Directional HDTV Antennas
DESCRIPTION Bigger in size, these antennas receive more signal power. Better for greater distances from signal source and areas with low signal strength. May work well in interior attic.
APPEARANCE Styles include element antennas. These antennas can be used to reject simple ghosting.
USE When mounted at rooftop heights (30 feet) outdoors, amplified antennas can be used in light green color code areas away from reflecting structures or low areas.


 Small Directional Antennas
Small Directional HDTV Antennas
DESCRIPTION Picture quality is excellent when no signal reflecting structures are around.
APPEARANCE Multi-element rooftop antennas.
USE Suitable for far edge of light green color code areas. Amplified antennas with rooftop mounting can be used in these areas if the area is free of signal reflecting structures and is not in a low area.
 Medium Directional Antennas
Medium Directional HDTV Antennas
DESCRIPTION Most popular rooftop antenna because of its modest size.
APPEARANCE Multi-element rooftop antennas.
USE If there are ghost producing reflective structures near TV receiver antenna location, this kind of antenna is best for yellow, green, light green and red color code areas. Amplified antennas with rooftop mounting can be used with the blue color code.
 Large Directional Antennas
Large Directional HDTV Antennas
DESCRIPTION Large antennas used in weak signal areas for maximum possible TV reception.
APPEARANCE Multi-element rooftop antennas.
USE Can be used in any color code area, but requires an amplifier and roof mounting for blue and violet color codes.

Note on South Carolina: The RF Channel Lists show only two channels, 8, 9, 10 and 13 less than 14. They are the only VHF Channels on the new HDTV line up. They'll need a broad VHF antenna for distant reception. The rest can be tuned on slender UHF antennas. Note, too, that many in-town homes are within 15 miles of towers where Indoor Antennas work just fine!
