This might work well, for instance, in a classroom setting where students need to build a device to take measurements at a location where the nearest WiFi access point is a kilometer away.ДЄdditionally, the directional nature of the Yagi-Uda means that you could potentially use this setup in a small-scale transmitter hunting game (assuming the transmitter was broadcasting a 2.4 GHz WiFi signal). If you're looking for a quick (and very cheap) way to boost your Internet of Things (IoT) device's connection, then this makeshift antenna is one good way. I tired the pringle can antenna and the Yagi beats it hands down. A yagi antenna is basically a telescope for radio waves.

Most likely you will need a longer cable to be able to. Easy to Build WIFI 2.4GHz Yagi Antenna: This antenna will extend the range of your WiFi or 2.4GHz devices (like surveillance cameras) into many miles and kilometers. This antenna is ideal for outdoor mounting and includes a the LMR-195 short built-in cable with RP-SMA male antenna connector. It comes with mounting equipment as shown. Then head over to radio shack or some online. This is a 16 dBi gain directional yagi antenna. Best best is to get a Wifi card that has a removable antenna like the one you have in your response to domdogg. I have not performed a line-of-sight distance test, but I'm willing to bet I would be able to connect to our building's WiFi at a farther range than with just the PCB antenna. 16 dBi gain outdoor yagi Wi-Fi directional antenna RP-SMA. I used a Yagi modeler java applet to generate the diagram.

Use Popsicle sticks to build the antennas backbone and hold it together. Trim paper clips to size and glue them to the template. With my completely unscientific testing, I figured I was getting around 6 dB of gain over the onboard PCB antenna, which isn't bad considering the backbone was crooked, the elements weren't exactly lined up, and there was no impedance matching whatsoever (among a whole host of other issues, I'm sure). Print out the scaled Yagi antenna template (download from next step).
