All-HF-Band, Horizontal, Center-Fed Antenna


All-HF-Band, Horizontal, Center-Fed Antenna is our old friend, the 80 meter halfwave dipole dressed up a bit. By varying the length of the 450 ohm ladder-line feeding the antenna, we can achieve an SWR of less than 2:1 on all frequencies on all HF bands with the exception of the lowest part of 80m

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, KV5R
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, AG5GW
I'd like to show you how I solved this problem, quickly and cheaply, and to great effect

Homemade Open Wire Feedline, W1AEX
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
