Antennas transmit or receive electromagnetic waves by converting electromagnetic radiation into electric current or vice versa. They transmit and receive radio waves and are widely used for radios and televisions
as also for point-to-point communication, wireless
LAN, cell phones, radar, and spacecraft communication.
Different types of antennas are used for different applications – for radios, televisions, and radar systems. Antennas are build for transmission of different frequencies and so they can be categorized by different frequency types. For instance radio antennas could be for frequency modulation (FM) or amplitude modulation (AM) broadcasting.
Television antennas could work for Ultra High Frequency (UHF), Very High Frequency (VHF), or both. Antenna types are also categorized in terms of customers’ needs varying with range like short, medium, or long range. Location is another way of looking at antenna types that include indoor, outdoor and attic installation.
Antenna types may also vary by style that usually focuses on appearance in terms of design. This may include antennas to be directional for gathering signals from a central location or be multidirectional to seek signals from towers transmitting from different locations. The varied kinds of antennas are used for television, citizen band, mobile, cell phone, police scanners, digital antennas, high definition, aerial and amateur radios.
With such varied applications for different types of antennas you can buy one depending on your use. Buying the best is certainly recommended as newer and more inventive versions come with complete instructions for installation. Indoor antennas are easy to install but may not have elevation for optimal signal reception. Outdoor antennas are installed on rooftops or even sides of houses, poles or decks. Attics are also used but mainly for aesthetic reasons.
