frequency and wavelength relation calculator Choosing a can based on calculation of diameter vs.Preview of work: Process of Building Thida’s cantenna I removed the radiator and sanded off the black paint where the radiator connected and retested – the signal was now 82 310 feet (so removing paint helped).Saturday’s testing of signal was 84 310 feet (so the extra length didn’t help).Added another can for length to see if that made the signal any better.Friday’s initial testing of signal was 84 310 feet.Decorated the cantenna by painting it black and adding lightning bolts.Drilled hole larger (1/2 in) with drill press for inserting radiator.Measured and punched a hole with a file at 1.63 inches from rear of can.frequency and wavelength relation calculator: Safeway Chicken Broth. 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)

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.

You can also use a real satellite dish and place the cantenna at the end of the arm at the position the TV antennas (the horn) usually go.We have a team of 2 people to build a directional wireless antenna (cantenna) for my IT103 Networking class. You can then make a wooden or aluminum frame to hold everything together in the right position.

You can find formulas for calculating the exact focal point or use trial and error since you will see your signal gain double or even triple when you get the curve and distance just right. It takes a bit of adjusting to get the curve of the screen and distance to the can exactly right. Instead of pointing the can at the signal source, point it at your screen which points at the signal so the back of the can points at the signal. To improve the signal even more - much more - cut a 2 foot (0.6 m) wide by 1 foot (0.3 m) high sheet of concrete lathing screen with 1⁄ 4 inch (0.6 cm) or smaller holes and curve it slightly to form a parabolic dish, similar to a TV satellite dish. This should be much stronger than the whip antenna you had before. Aim at source and adjust to get the best signal.
