| 11. | The individual elements are most commonly half wave dipoles, although they sometimes contain parasitic elements as well as driven elements.
|
| 12. | That is, they reradiate power which they receive from the driven element ( they also interact with each other ).
|
| 13. | An antenna may have more than one driven element, although the most common multielement antenna, the Yagi, usually has only one.
|
| 14. | "Doin'Dirt " is a disco and electropop song with high energy and beat-driven elements which lasts for three minutes and thirty-one seconds.
|
| 15. | The driven elements are fed by a network of transmission lines, which divide the power from the RF source equally between the elements.
|
| 16. | The log periodic antenna is similar in appearance to a Yagi, but all of its elements are driven elements, connected to the transmitter or receiver.
|
| 17. | The radiation resistance of the dipole increases with this spacing, so the spacing can be adjusted to match the driven element to the feed line.
|
| 18. | The wave generated by the driven element ( green ) propagates in both the forward and reverse directions ( as well as other directions, not shown ).
|
| 19. | Let the driven element be designated 1 so that " V " 1 and " I " 1 are the voltage and current supplied by the transmitter.
|
| 20. | The reflector is easily identified as being a bit ( 5 % ) longer than the driven element, and the director a bit ( 5 % ) shorter.
