It is possible for one to make an inexpensive wifi antenna to be used to amplify wifi signals. When well designed, the cantenna allows for the distance between the wirelesses device to be increased without any problem. The procedure of making this simple wifi cantena is equally simple; all you need to do is to find a can which is less than 4 inches in diameter. Making use of a longer can will give you better results compared to when you use a shorter can. It is important that you check the angle of sweep if you want to reduce external interference. In some cases, you may not get a single long can to use. In such a case, you may be forced to soldier several cans so that you get the required length.
The next important thing you need to do is to calculate the distance where you will drill the hole. You need to punch enough holes on the can. The drilling of the wholes must be carefully done to ensure that you do not spoil the tin. The next thing you must do is to buy a small brass wire which should be soldiered on the tin. This should be done carefully for better results.
You must then place an RP-SMA right angle connector in the hole so as to secure it on the can. You should use a rubber gasket and slip it around the connector. The antenna cable must be tightly fitted to this connector, and the connector held in place on the can.
You may be required to attach a wire tail to the adaptor so that it performs better. The wire to be used in making the tail should be thin but should reliable and capable of lasting for long. You may be required to create a stand using a thick wire. Alternatively, you may make use of a tripod stand but you must ensure that the stand you make allows the cantenna to rotate and find signals.
After the exercise, it is necessary that you test your cantenna to establish if it is capable of giving the required service or not. If you want to improve the signal it may be necessary for you to cut a concrete lathing to be curved in to a parabolic dish.
After successfully mounting the can, you should test it while pointing it to the source of the signal. Establishing the focal point could be necessary if you want to get the best signal. If the testing is successful, you may be required to make a wooden aluminum frame which holds what you have made in the right position.
If you have a satellite dish, you may put your cantenna closer to it to boost the signal. However, if the wifi signal is not strong, you may need to dismantle everything and start a fresh. It is expected that the cantenna should work well after a little effort. If it is working you need to check the strength of the wifi signal you are receiving. If it is not strong, a few modifications may be needed.
