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 arrays 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.
