The type of wireless system what you are using and its location will determine which type of wireless antenna you should choose.
Directional antennas and omni-directional antennas are two basic types of wireless antennas. Directional antennas are commonly utilized in point-to-point systems, sometimes also use in point-to-multi-point systems while omni-directional antennas are most often employed in point-to-multi-point systems.
A directional wireless antenna is primarily used to transmit a signal from one building to the next building while an omni-directional wireless antenna is typically used as a type of main antenna which distributes a signal to other wireless devices in an office, business, or home. Directional wireless antennas are also known as Yagi antennas, backfires antennas, dish parabolic antennas, grid antennas,wall mount antennas or panel antnenas. Omni-directional wireless antennas usually go by the names such as omni roof mount antennas, omni fiberglass antennas , rubber ducks, decorative antennas(like lawn-lamps antnenas, lamp-standard antennas, ceiling-lamps antennas, mushroom antennas, stone antennas, tree antennas) and vertical omni antennas.
Directional Panel Antenna Yagi Antennas Omni Antennas
Lawn-lamps antnenas, lamp-standard antennas, ceiling-lamps antennas, mushroom antennas, stone antennas, tree antennas are all decorative antennas. They are the best choice and well suited for use in a park, hospital, community, school, or street where don’t want people to know there’s an antennas is standing by him/her. So usally decorative antennas will cost more than a normal antennas. A Yagi antenna is a low-cost antenna that has a signal range of more than 1 mile (1.6 kilometers) and can be mounted outdoors on a pole. The backfire antenna is less expensive than the Yagi and is only 10 inches in diameter, making it well-suited for use in outdoor areas where space is limited. Panel antennas, grid parabolic antennas and dish type antennas are large and powerful long-range outdoor antennas that can withstand very high winds; they can also be much more expensive than a Yagi antennas, however. Vertical omni-directional antennas are very sturdy and hold up well in nearly all outdoor weather conditions. Roof mount wireless antennas have a less obstructed line of sight indoors and are able extend through walls also.
Wireless systems can be set up as a point-to-point or point-to-multi-point network. Point-to-multi-point systems are commonly used for sharing a high-speed Internet connection within a single building, such as a home or office. Point-to-point systems typically involve wireless points in two different locations, such as transmitting a wireless signal from one building to another building. They can also be used for wireless access points often found at airports, truck stops, hotels, and coffee shops. These access points allow patrons to access the Internet using their own portable wireless devices.
Once you have become more knowledgeable about wireless antennas and their various applications, it will become somewhat easier to choose the best antenna for your particular needs. You should keep in mind that your business and personal matters often rely upon the performance of your wireless system. You may also want to plan for future uses that you may have for your wireless system as well. More knowledge about wireless antennas on www.chinaantennas.com.
