You may have heard of the Pringle tube antenna, which was on the right tracks, but this is the science-perfect version.
From what we've read wireless networks use these things called radio waves, we can't see them but we have empirical evidence they exist. Using the brains of this chap, it seems a 100mm diameter can boost these waves to improve performance.
1. Let's take this lot of junk and turn it into a Wi-Fi boosting antenna.
2. The key part is the can. Our measurements are based on a 100mm diameter one. Ideally, it needs to have smooth sides. We found paint tins are the best solution. We're making do with a potato tin here just for demonstration purposes.
3. Effectively this works with any diameter can in the range of 90mm to 110mm, check out this online calculator for your own specifics.
To fit the N Connector a 15mm hole is required, with its centre 44mm from the sealed end.
4. For testing fix it with Blu-Tack, you can bolt it into place afterwards.
5. To pick up the signal, a receiving antenna is required, use a bit of solid copper from 30A mains wiring or a brass nail cut to 31mm in length. Solder this in place.
