What you can do with this?
You can design Yagi antenna to boost network signal strength and bandwidth to get better download and upload speeds for any network connection using for example 3G, 4G/4G LTE, 5G and WIFI.
You need to know which frequency to build it for, search online or ask your service provider which frequency connection is working at.
You also can create Yagis for ham radio use if you know which frequency band you need it for.
