Types of Antennas

Click:239Date:2011-09-26Information Source:

Following is a description of different types of TV antennas, both indoor and outdoor. Information provided includes the type of antenna, a general description of how the category of antenna performs, a general description of the physical appearance of the antennas, and where they may optimally perform in relation to the color code of the station you want to receive.

Indoor Antennas 
Due 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 CEA performance specifications for indoor antennas in households that can use indoor antennas.

Outdoor Antennas
Look for this mark on outdoor antennas, based on the colors of the stations you want to receive:
Small Multi-directional
Description  The smallest of TV antennas, they receive equally well from all directions. 
Appearance  Good looking designs including novel shaped disk and patch antennas, and antennas that attach to satellite systems. 
Use  In yellow color code areas where signal strength is highest and away from reflecting structures or low areas.

Medium Multi-directional 
Description  Somewhat larger and slightly more powerful 
Appearance  These antennas include novel stick, wing shaped or disk antennas with long elements. 
Use  Green color code areas. An amplified antenna is recommended in the green area anytime a long (20 feet or more) cable run from the antenna is required, or when more than one device (TV or VCR) is to be used with an antenna. They work best away from reflecting structures or low areas.

Large Multi-directional 
Description  Bigger in size, these antennas receive more signal power. Better for greater distances from signal source and areas with low signal strength. 
Appearance  Styles include element antennas. These antennas can be used to reject simple ghost situations. 
Use When mounted at rooftop heights (30 feet or higher) outdoors, amplified antennas can be used in light green color code areas away from reflecting structures or low areas.

Small Directional 
Description  Antennas that act like large multidirectional on channels 2-6 but on higher channels these antennas start to have useful ghost reducing effects. 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 
Description  Most popular rooftop antenna because of its modest size and ghost reducing characteristics. 
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 
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. Amplifiers are not recommended for yellow color codes.
