Wifi hi gain antenna

The mega antenna is going to boost your Wifi signals for sure. The comparatively large antenna has the dimensions of A simple antenna that is quite popular on all VoIP devices. The Omni-directional antenna has a 9dB gain and is compatible with all The antenna is approximately 15 inches in length and like most top products, it is omni directional. The only high gain antenna on our list that that comes with its own easy to connect USB extension which is about 1.

The device is Dual-Band All the antennas are covered in 1-year warranty. Your email address will not be published. Notify me of follow-up comments by email. Notify me of new posts by email.

Loading Comments It provides a good impedance match to coaxial cable when used as the yagi wifi antenna's driven element. In free space, a folded dipole has a ohm impedance at resonance, but the impedance drops drastically when parasitic elements are brought into close proximity.

Print and use this plan view when building the 15 element yagi wifi antenna. Print and use this plan view when building the 20 element yagi wifi antenna. This high gain wifi antenna can be constructed in a couple of hours and requires some measuring, cutting, bending, and bolting of metal. Use caution around the sharp edges. When finished, put it up and enjoy a very durable antenna that provides outstanding wifi performance.

Assemble the yagi wifi antenna following the steps below, starting with preparation of the boom, followed by mounting the elements. After the elements are mounted, a suitable connector is added, and the antenna is tested over-the-air.

Keep in mind that it can be connected to most usb wireless adapters by cutting the circuit board antenna trace and patching in a pigtail feeding the antenna. After all of the elements are measured, cut, and mounted, the antenna should resemble the finished yagi pictured below.

Connect the pigtail or connector to the driven element. Then connect the wi-fi adapter or wireless router to the antenna and start checking over-the-air signal strengths. Note that the antenna may be sensitive to polarization: when the antenna seems to bring in the best signal, rotate it to find the best polarization.

Mounting the antenna is possible using commonly available hardware, such as 90 degree angle brackets, U bolts, or even velcro. Closeup of the wifi yagi feedpoint.

Keep the leads short! The completed wifi yagi antenna. For the most practical method of signal checking, consider using a wifi auditing utility such as Kismet or Slitaz Aircrack-ng.

Either of these will produce a rapidly updated received signal strength indication that is useful for comparing or aiming wifi directional antennas. Make a set of measurements for any desired wi fi access points on the original antenna, then make a new set for the yagi wifi antenna. The antenna should exhibit high forward gain and front-to-back ratio. A prototype in fact performed as well as the wi-fi 12 turn helical antenna shown elsewhere in these pages.

Again, for ultimate performance over long distance wifi links, use a short version of the yagi to feed a parabolic reflector as well as a high powered wifi adapter.

Watch a video the wi fi yagi antenna construction on Youtube:. Someone made a very well constructed wifi yagi with a plexiglass boom! Their video adds some hip hop music and slick graphics to showcase this design. It retains attributions and links to this page, so the webmaster is happy to see it! There are others too! One person, in China, built one and created a smart-phone access point covering a long section of street.
