Wifi Antenna? what is it.

A wifi antenna is an external antenna connected to a computer related device that uses the 802.11 standard. They can be used to connect: Router to router, computer to computer, or router to computer(s). Using wifi saves you the hassle of having to wire a whole network, and gives your computers the freedom to be where they want, within your wifi's range. There are many different kinds of wifi antennas that you can get, but selecting one depends on what kind of network you want to set up. If you want to set up a network that is widespread but less in range you would use an omni directional antenna. Most routers, such as my Linksys wrt54g router, comes equipped with 2 omni directional antennas out of the box. Some router let you have the option of swapping antennas though. If your looking to do a more directional connection (say you and your neighbor want to share wireless) you would want to go more along the lines of a yagi wifi antenna, which is directional and high powered. You could connect a yagi antenna to your router, or just a simply USB interface right to your computer. Now lets say you want a very directional connection (maybe trying to connect to somebody a mile or two down the road), You may want to check into a grid wifi antenna. These bad boys are modeled after a satellite dish. They are very directional and very high powered. Whether you choose directional or not, going wifi can make your life easy and more flexible. If your looking to buy one of these antennas please check out my store Thanks for reading!
