What Is Omnidirectional Wi-Fi Antenna?

What Is Omnidirectional Wi-Fi Antenna? A vertical antenna or terminal antenna that typically radiates its signal equally well in 360degree directions, we called it omnidirectional Wi-Fi antenna. The signal strength decreases with distance and is often weaker directly above and below the antenna; a longer vertical frequently gives better performance. An omnidirectional antenna can transmit signal in 360degree, and can receive signals from all directions also. Many wireless routers and Wi-Fi access points use an omnidirectional Wi-Fi antenna to reach all of the rooms in a home or office. It is called point to multi-point. Of course omnidirectional wifi antennas use in point to point systems also.


Omni ceiling antennas, omni fiberglass antennas, omni mushroom decorative antennas, omni vehicle antennas, omni terminal antennas,omni stone decorative antennas,omni lawn-lamps decorative antennas, omni lamp-standard decorative antennas, omni Simulation tree decorative antennas, omni smoke ditector antennas are several different designs for omnidirectional antennas. Some designs have more gain—signal amplification and reception sensitivity—than others. One of those terminal and vehicle antennas with the least gain is commonly used on most consumer wireless access points and routers. Often known as the "rubber duck," or terminal antennas. it is named for the flexible rubber sheath that makes the Wi-F antenna more durable. It is basically a piece of coax cable with a simple metal decoupler separating the shielded and unshielded portions of the cable. Compared to a perfect isotropic antenna, this design has a typical gain of 2-3dBi. Like the one as below:

Omnidirectional Wi-Fi antenna with about 6-9dBi gain can be created. An omnidirectional Wi-Fi antenna with better gain is a long piece of copper wire with several carefully crafted loops in it; a gain of 4-15dBi can often be produced, depending on the length and number of loops used. The wire is frequently encased in some form of plastic tubing to preserve its critical shape. Vehicle megnetic mounted antennas are variations on this design. If space is very limited, a lower-gain alternative is a quarter-wave "spider" antenna—a radio frequency connector with a metallic base, a bit of coax and four stiff wire "legs" to form a ground plane.

When people use omni Wifi antennas in a home or office environment, a directional Wi-Fi antenna may also be used with the omnidirectional Wi-F antenna also. A directional Wi-Fi antenna, it focuses the transmitted signal in just one direction; it also receives signals mainly from that same direction. The gain of a directional antenna is often much more higher than an omnidirectional one, by 15-24 dBi or more like 32dBi. Directional Wifi antennas are including of sector panel Wifi antennas, directional grid antennas, directional dish antennas, directional yagi antennas, directional wall mount antennas, directional small flat panel antennas. The signal is usually concentrated with the help of a metallic cylinder, dish, mesh or other reflective surface; this makes it ideal for longer-distance point-to-point communications.. Both types of wifi antennas can be used together—an omnidirectional one to serve a small area, in combination with a directional one to connect to a distant network.
Wifi antennas also can be categories in outdoor Wifi antenna and indoor Wifi antennas. Usually, most of directional Wifi antennas are outdoor Wifi antennas, and most omni Wifi antennas use indoor.

Build a Wi-Fi antenna or purchasing one ready-made are all impossible. Many books and websites illustrate how to assemble different types of Wi-Fi antennas. They can often be constructed using simple tools and inexpensive materials. Some creative people have even built directional antennas from tin cans and cooking woks. A large number of commercial vendors sell mass-produced Wi-Fi antennas as well. wifi antenna, China antenna, directional indoor antenna manufacturer, supplier, factory
