Chose a can based on calculation of diameter vs.Made a punch mark with a file and drilled about ½ inch hole. I marked a spot on the can at 1.63 inches from the rear of the can. Measuring and drilling a hole for mounting radiatorīased on the calculation, the distance of where I should mount the radiator from the rear of the can is 1.63 inches.
Lower Cutoff Frequency Check in MHz (make sure 2412MHz for 802.11g)
Safeway Chicken Broth can (diameter 4.25 inches)Ĭan calculations: Can Diameter in inches:. Materials and tools used for the project: frequency and wavelength relation calculatorīased on research, a can with a diameter range of 3 to 5 inches would give the best performance. Then, we will turn in the best cantenna to Rudy to test for our grade.Ĭhoosing a can based on calculation of diameter vs. We need only one cantenna for the team, but we decided to build our own cantenna individually and choose the better of the 2 based on: 1) Efficiency (strength – who had the lower test score?) 2) Appearance (Design – most creative for best rating by classmates). There are scientific principles at work so we used a cantenna calculator to do a little research before we broke out the drills and spray paint! The size, shape and design of the can is our decision. 
We will be using a can and a special device called a ‘radiator’ that Rudy will supply. We will work together to research and build the device. We will individually create a ‘build’ web log that chronicles the experience. We have a team of 2 people to build a directional wireless antenna (cantenna) for my IT103 Networking class.
