To improve the reception of a WiFi or WiMax signal, special antennas such as Cantenna are often used. They are made from ordinary cans. Despite this, such an antenna sometimes works even better than many factory ones.
Instructions
Step 1
Take any tin can that is higher than the diameter.
Step 2
Rinse thoroughly and then dry the jar. If it has a sticker, remove the sticker during rinsing.
Step 3
In the side wall of the can, towards the bottom, drill a small hole corresponding to the bore diameter of the connector.
Step 4
Scrape the varnish around the hole on both the outside and inside of the can.
Step 5
Place the connector in the hole so that the plug can be connected to it from the outside and the solder pin is inside the can.
Step 6
Calculate the length of the radio wave emitter that will be inside the jar. Scientifically, it is called a vibrator. Calculating its length manually is difficult, so use the special Javascript calculator located on the next page
Step 7
Next, be careful: the diameter of the can will have to be manually converted from millimeters to inches. Then enter it into the form. Enter the values of the upper and lower limits of the range in megahertz there.
Step 8
Press the Calculate key. You will get the lengths of the wave, half wave and 3/4 wave vibrators. If the wave vibrator does not fit in the jar, make a half-wave one, and if it does not fit a half-wave one, make a 3/4 wave one.
Step 9
Use thick copper wire as the material for making the vibrator. Once you have cut a length from it, simply solder it to the center pin of the connector inside the jar. If soldering is inconvenient, remove the socket, solder the vibrator to it outside the can, then put it back together with it.
Step 10
Point the antenna towards the access point or base station. Fasten it well and connect to a WiFi or WiMax adapter. If it will be located outdoors, protect it from atmospheric precipitation with a thin plastic wrap. Never use an antenna to connect to networks without the permission of their owners. Remember that even open chains in restaurants and similar establishments must not be used outside of their premises.
