In this video, I will show you how to construct a dual-band long-range repeater for 2. In this Instructable, I make a battery-powered portable long-range 2. It can also be used to find open WiFi access points on the go.
It is working pretty well. Just the range is a bit short. I found a solution to this problem. This mode is much more low level. Do you want to boost your WIFI? Looking for a DIY antenna? You can build your own WIFI antenna by having a look at this tutorial. In this video, we learn to make a powerful WiFi antenna for a long-range signal catcher.
Home Made 2. It works great too. I wanna show you how to make 1km range wifi antenna at home easy way. You can see my another log range Wifi antenna video from CAD or end screen. Build this wifi antenna when you want results FAST and have just a few inexpensive tools and supplies available. It will greatly extend your ability to reach wifi access points - well beyond the limits of the dipoles supplied with most routers and some wireless adapters.
When connected to a typical USB wireless adapter, the performance is excellent. When connected to a high powered wifi adapter, the performance is astounding! Forget about building those overly hyped wifi cantennas - they don't perform anywhere close to the yagi antennas depicted here. This antenna works best when connected to a wifi adapter, and it works very well as a single router antenna to extend the range of an access point.
Read more below for instructions and a narrative of how they were designed. If your goal is to get wireless internet from another building and use it indoors, you should instead consider using a wireless bridge. If you want to provde strong wireless internet coverage to an area, but cannot provide a fiber optic or ethernet cable to your wireless router, again consider using a wireless bridge to substitute for the unavailable cable, and connect the bridge to the router.
A wireless bridge is a better solution for situations such as:. If you are interested in building a high gain wifi yagi antenna, continue reading below for the details. The yagi wifi antenna design depicted here can be built in just an hour or two, and it works great! It is computer designed, made of wood and wire, and provides high gain and directivity. It is directional - favoring wi-fi signals in one direction and rejecting interference from the sides or behind the antenna. The 15 element wi-fi antenna provides over 15 dB of gain multiplying your effective radiated power by 31 , while the larger 20 element wifi antenna provides over 17 dB of gain multiplying your effective radiated power power by Front to back ratio for both antennas is about 22 dB.
Yagi wifi antennas can be rather difficult to build, but it can be done if you measure precisely and cut precisely. The hard mathematical design work for the wifi antennas shown here was accomplished elegantly using a yagi antenna modeler, created by Kevin Schmidt W9CF and Michael Lee.
The on-line antenna modeler initially starts with several examples tailored for operation in the amateur radio bands. One of the best designs is the classic K1FO yagi. By following a few steps, the antenna can be scaled for the 2.
The elements list will show each antenna element, from the reflector element 1, position zero mm , to the last director. Do not use a different metal or a different diameter of metal for the elements, or performance will suffer. Changes in element diameter, metal type, or design frequency will need recalculation and the generation of a new elements list. These dimensions work quite well:. Below is a graphic, meticulously adapted by AB9IL from the modeler, which shows element lengths and positions along the boom, measured from the reflector location zero millimeters.
In my case, I just connected a single thin strand of copper wire between the active element of the strip antenna and one end of the loop of the driven element. The performance was pretty spectacular for this easy to build antenna. I was able to see the WiFi of a hotel that was 2 miles away from my home. The most difficult part was connecting the antenna to the USB modem. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.
