Welcome to tech genie, I'm Andrew and in this episode I will show you how you can build an biquad antenna, for a wireless network connection and for internet. This antenna if constructed with care, can create a link at a 2.5 km distance, tested on the field, 2 antenna's connected one to each other can gave 6 megabits of free bandwidth in my test. This is the cheapest way to go wireless, and if you are a person that is on low budget, this will surely help you in grabbing internet services on the quick. The quad element of the biquad is made from copper, the bent element is made at 90 degrees , at a distance of 3.05 mm from each other. You just drill a hole in a PCB, that's the easiest way to have an reflector,and mount the N connector to the PCB with it's nut and you are ready. Just solder the element to the N connector next and you've done it, you have a working Biquad antenna.
For the Cantenna you will need a coffe can, in my case, and you will drill the hole in the can in the place that is provided to you by the cantenna calculator after you have measured the can.
Drill carefully and before you make anything else, solder your cantenna element that is 3.05 mm on the N connector, just like in the case of the biquad, but this time you will solder a copper wire to the N connector and you will trim it at the 3.05 mm mark, that will make the element function on 2.4 Ghz, that's the frequency that we are using in Wireless. Screw the nuts and bolts, secure the N connector and plug the pigtail to the Cantenna and begin to scan and use it to connect to the Internet.
