folded dipole sentence in Hindi

Examples

1. Half wave folded dipoles are often used for FM radio antennas; versions made with twin lead which can be hung on an inside wall often come with FM tuners.
2. The transmitter site was at Casseldon Place on the Melbourne CBD, which provided around 25 km coverage from a 250 Watt FM transmitter through a single folded dipole antenna.
3. Another common design is the folded dipole, which is essentially two dipoles placed side-by-side and connected at their ends to make a single one-wavelength antenna.
4. The driven element is typically a ? / 2 dipole or folded dipole and is the only member of the structure that is directly excited ( electrically connected to the feedline ).
5. Compared to a dipole or folded dipole, it then transmits less toward the sky or ground, giving it a slightly higher gain ( about 10 % higher ) in the horizontal direction.
6. Rather than feeding each dipole at its center, which requires a " tree " transmission line structure with complicated impedance matching, multiple dipoles are often connected in series to make an elaborate folded dipole structure which can be fed at a single point.
7. Likewise with CATV, although many broadcast TV installations and CATV headends use 300 ? folded dipole antennas to receive off-the-air signals, 75 ? coax makes a convenient 4 : 1 balun transformer for these as well as possessing low attenuation.
8. Transmissions took place from a single arrowhead antenna mounted on the nose of the aircraft . This consisted of a folded dipole with a passive director in front of it, both bent rearward at about 35 degrees, projecting from the nosecone on a mounting rod.
9. 9 . Peiyuan Qin, Andrew Weily and Y . Jay Guo,  A Frequency Re-configurable Quasi-Yagi Folded Dipole Antenna, IEEE Transactions on Antennas and Propagation, vol . 58, no . 8, pp . 2742 2747, August 2010.
10. The design has almost double the radiation efficiency of the HF folded dipole of the same length and is nearly half the size of other traditional HF wire antennas such as the " Australian travelling wave dipole " The standard size Robinson Barnes antenna is only 27m in length.
