1. The driven elements are usually dB greater than a simple dipole antenna. 2. :Yagis consist of 3 basic components-the reflector, driven element and the director. 3. The driven element is attached to the black box next to the reflectors. 4. They are also widely used as driven elements for rooftop Yagi television antennas. 5. This would tend to cancel the radiation of the driven element . 6. Bowtie driven elements are often used for wide bandwidth applications like television antennas. 7. From left to right, the elements mounted on the boom are called the reflector, driven element , and director. 8. The directors are slightly shorter than the driven element , while the reflector ( s ) are slightly longer. 9. The driven element is fed at centre so its two halves must be insulated where the boom supports them. 10. Consider a Yagi & ndash; Uda consisting of a reflector, driven element and a single director as shown here.
