An antenna is a metallic structure that captures and/or transmits radio electromagnetic waves. Antennas come in all shapes and sizes from little ones that can be found on roof to watch TV to really big ones that capture signals from satellites millions of miles away. Outdoor antennas are products you install on roof, in aloft or on the side of your residence.Outdoor antennas are more expensive and difficult to install, but are necessary for adequate reception in peripheral areas far from television stations. Outdoor antennas are ideal for homeowners who live in remote areas where reception could be a problem.
Outdoor antennas are usually more powerful than indoor antennas so they are generally more reliable. Outdoor antennas that are Omni-directional, directional, high-gain, 2.4GHz and 5GHz that will help expand Wi-Fi network. The global Outdoor Antenna Market is segmented on the basis of type, rating system, product type, application, and region. On the basis of types, the global market is segmented into directional, non-directional and multi-directional.
Directional antennas must point toward the transmission tower to receive the signal while multi-directional antennas can receive signals when not pointing toward the transmission tower. Non-directional antennas radiate unwanted radio waves in the environment, and conversely pick up noise from every direction. On the basis of rating system, the global market is classified into yellow, green, light green, red, and blue, purple.
Antenna webs rates outdoor antennas with a 6-color rating system. These ratings should appear on the outside of a CEA-approved product such as Yellow - small multi-directional, Green - medium multi-directional, Light green - large multi-directional or small multi-directional with pre-amp, Red - medium directional, Blue - medium directional with pre-amp, and Purple - large directional with pre-amp. The colors are designed to help select an antenna without having to compare specifications between models.
On the basis of product type, the global market is classified into Cantenna, Yagi-Uda array, ANT005, High Definition Antenna, 4220 type, Whip (rod) antennas, Dipole antenna, and parabola antenna. 4220 type: is a medium directional outdoor antenna that has a range of 20 miles. It can attach to the roof, side of the house or the overhang where gutters would go.
Cantenna is the term referred to generic do-it-yourself antennas using a simple cylindrical design. It supports 2.4 GHz signaling with gain up to 12 dBi and a beam width of about 30 degrees. Yagi-Uda array is another type of directional radio antenna that can be used for long-distance Wi-Fi networking. These antennas are typically used to extend the range of outdoor hotspots in specific directions, or to reach an outbuilding, as television antennas and so on. They have strong directivity, and must be aligned in the direction of the transmitting station.
Yagi-Uda is a dipole antenna with director and reflector elements attached to direct and reflect the radio wave. Parabola antenna is used for receiving satellite broadcasts. These antennas have very strong directivity and require fine directional adjustment, but they can use the power of the radio waves efficiently.
Whip (rod) antennas are used for mobile phones and the Non-directional antenna with equal sensitivity in any direction. Dipole antenna: used for amateur and so on. Most widely used class of antenna. These produces a radiation pattern approximating that an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each end.
Geographically, the global market is segmented into North America, China, Europe, Japan, Taiwan, and Korea. The key players are B&B Electronics, Omron, Honeywell, Schneider Electric, Texas Instruments, TE Connectivity, Phoenix Contract, Laird Technologies, Murata, Digi International, Linx Technologies, HARTING, Radiall, Taoglas, and Bulgin.
