WIFI antennas Directional
The wifi antenna is the passive element that captures the energy it receives from the station. A WIFI antenna is used to detect the WIFI signal that is in its scope of coverage and as well get connected to be able to access the Internet. The WIFI antenna can go coupled devices very varied as WIFI adapters, USB WIFI router, access Point or WIFI computers, tablets, cameras, WIFI and a plethora of terminals. A wifi antenna works thanks to its electromagnetic frequency complies with the standard 802.11 that on the passage of time has been updated to be improved in successive versions, each time allowing more speed: 802.11 a, 802.11 b, 802.11 g, 802.11 n etc
The WIFI antennas directional or policies are those that by their form concentrate most of the radiated energy so focused to a point or direction. A WIFI antenna directional normally increases the power emitted towards the receiver or from the transmitter and prevents interference.
Types of Directional antennas powerful are the antennas, Yagi antennas Panles, sectorial Antennas and Parabolic antennas WIFI.
Parabolic Antennas for WIFI are designed for exterior use. Are the larger antennas and more powerful. With these antennas you can make WIFI connections 3km, 5km, 10 km, and up to a WIFI connection to 50km. The best installation is achieved when you place two antennas ALFA AGA grid faced with stable connection. You can dock it to any WIFI card (output N). Antennas are antennas WIFI directional grid for 2.4 Ghz and 5Ghz.
