The N4GG Array
- Need a simple, nearly invisible wire antenna with reasonable gain, lowangle radiation (for DXing) and multiband capabilities? Check out this
long-overlooked design that requires no antenna tuner
Effect of tower coupling on an array
- It's well known that a nearby tower can affect the performance of a vertical array
, this article by NK7U describe measurements and prove interaction.
The 4-Square Site
- 4 Square Vertical Array
website dedicated to vertical array

Phased Array Adjustment
- KM5KG article presents a lumped-parameter tee-network model of the coupling between radiating elements in a phased array
in order to provide a physical and intuitive understanding of phased array
operation and adjustment interactions
- Bobtails are vertical array
s that look like the letter "E" turned 90° clockwise onto its tails. They have 3 quarter wave vertical elements and are one wavelength long. The Half Square is a shortened Bobtail- it has 2 quarter wave vertical elements and is a half wave long.
