I made my first antenna. It’s a 2 meter yagi using the recipe on this web page: http://www.ccars.org/Projects/TapeYagi/index.htm
It works but not quite as well as I expected. After my first test, I found a stray strand of wire shorting the center and shield conductors where I separated them. After fixing the stray wire, I got much better performance and it works great!
Eureka!
