The "Clearstream", "Db", and "Lacrosse" series antennas will work very well is most locations, we have researched the largest metropolitan areas in the U.S. and provided a summary of which of these antennas work best in which cities.
Some may learn that one or more of their towers are not in the same general direction and will need a VHF antenna. Examples would be: You can pick up all your UHF channels because they are all in the same general direction and being that UHF antennas are multidirectional you will have no problem. But their will be instances where customers may have a few VHF channels that are either on the low end feq. (2-6) or they are not located in the direction of your UHF channels.
If you do not live in a major U.S. city, this page will walk you through the process of identifying the type of antenna that will perform the best.
Check the button that says "Show Digital Stations Only" and this will bring up a list like the one above assuming you live in close enough proximity to any transmitters. The CEA site provides this excellent information, but there is one issue that people have with it. For one city, it will often recommend a variety of antennas one should get to receive HDTV signals. Obviously, most people do not want to outfit their home with numerous antennas, so some trade offs are typically made. From this chart you can determine the type (UHF or VHF), power, and style antenna that should work best.
Look under the columns titled "Antenna Type" and "Frequency Assignment" . If you need to receive low frequency VHF stations (Channels 2-8) you may need a VHF antenna.
Look at the "Miles From" column on the far right side of the chart and then choose from the following:
In some cities like New York, Chicago, and Los Angeles, all stations are broadcast from one central area, the Empire State and GE Buildings in New York, the Sears Tower or Hancock Building in downtown Chicago, and Mt. Wilson in Los Angeles. In other cities like St. Louis, the transmitters are scattered around the city.
Check the "Compass Orientation" and if all of your desired stations are transmitting from the same area or within 20° of each other you can use a uni-directional antenna. If the transmitters are positioned more than 20° apart, it is best to use a multi-directional antenna. It is important to note that most multi-directional antennas will work in place of uni-directional antennas, but you may pick up some multi-path distortion.
By clicking on the "View Street Level Map", you can get a graphical representation of your compass orientation.
