Types of AntennasAntennaWeb has been designed to take the guesswork out of choosing the correct outdoor antenna. To simplify choosing an outdoor antenna, the Consumer Technology Association has created a color-coded labeling standard classifies antennas by type. Within each type, the features, designs and prices of antennas may vary greatly between models and manufacturers but the labeling standard ensures all models within a given type will have similar reception qualities.
Following is a summary of outdoor antenna types. The summary provides a general description of each type's size and appearance as well as installation guidelines for optimal reception of the desired local channels.
Guide to Antenna Box LabelingWhen purchasing an antenna, look for the CTA-certified antenna mark for outdoor antennas (which corresponds to the colors on your stations list). There is also a CTA-certified indoor antenna mark, which does not apply to this mapping system, but certifies that your indoor antenna will work in geographic areas that are appropriate for indoor antennas.
CTA-certified Antenna Mark for Outdoor AntennasAntenna color codes are broken into six different zones. These zones identify the different types of antennas that are required for a consumer to receive optimal reception. Typically, the closer consumers live to the signal tower, the better reception they will receive. They may also be able to use an indoor antenna versus an outdoor. The farther away a consumer lives, the opposite is true. However, there are many variables that impact exactly which antenna a consumer will need.
Indoor AntennasDue to multiple variables in determining good reception in a specific location with indoor antennas, these antennas are not included in this mapping system. This mark, however, assures that an indoor antenna meets or exceeds CTA performance specifications for indoor antennas in households that can use indoor antennas.
