Websites that allow users to determine the nearest broadcast towers include Channelmaster.com and Antennapoint.com. Anntennapoint.com lets users enter a city, state, ZIP code, address or map coordinates into its system to find the nearest towers. Channel Master also lets users search for towers in their area by address.
Channelmaster.com explains the difference between the different types of broadcast tower and why that could affect what sort of an antenna a consumer needs to buy. There are three basic types of tower. The first is directional and works best for single direction signals of over 50 miles. The second type is multidirectional. This type of tower serves multiple communities that are close together. Finally, the omnidirectional tower works best within an area of 50 miles or less.
