In this video, I show you how I am designing a Quagi antenna (BiQuad/Yagi combination) and why I don't build the computer generated models. This is for long range FPV and long range WiFi use. I should be able to get a WiFi signal from 5-6 miles away and as far as FPV... this is a 65 mile video link... maybe more.
I fully admit that I could get this closer by adding in a few more variables to my program, but not amount of programming will replace real-world testing. I go through this with all of my antenna designs to verify that when the end user puts a VAS antenna on their equipment, their signal is the best it can possibly be.
