Proposed kantenna is dual band
The cylinder and conical portion of the can may consist of metal-coated .
Although some designs are based on a Pringles potato chips can, this tube is too narrow to increase the 2.4 GHz signal by a useful amount, although at 5 GHz it would be about the right size.
However, a cantenna can be made from various cans or tubes of an appropriate diameter. Some designs include a pole mount to elevate the cantenna.
At 2.4 GHz and 5,5 GHz, losses can occur if the cable from the cantenna to the Wi-Fi circuitry is too long. A more efficient kantenna can be made by minimising this length or connecting the cantenna directly to the Wi-Fi circuitry.
