Finding the Velocity Factor of Coaxial Cable
a tutorial in use of Velocity factor solver to find the velocity factor of a sample coaxial transmission line using an antenna analyser

Ham Radio Ladderline
First let's dispel the greatest myth in antenna theory: Antennas must be resonant to be efficient. Baloney! It just ain't so!

Home Brewed Antenna Ladder Line
I'd like to show you how I solved this problem, quickly and cheaply, and to great effect

Homemade Open Wire Feedline
With a few simple tools and a little effort you can make your own open-wire line that is superior in many ways to the window line that is commonly sold by antenna product vendors
