turnstile antenna मीनिंग इन हिंदी

उदाहरण वाक्य

1. This is the case, for instance, between the crossed dipoles used in the turnstile antenna.
2. A turnstile antenna with its four arms in the horizontal plane, likewise transmits horizontally polarized radiation toward the horizon.
3. Axial mode turnstile antennas are often used for satellite and missile antennas, since circular polarization is used in satellite communication.
4. Transmitting antennas consisted of two fiberglass slot antennas in the body of the satellite itself and four flexible whips forming a turnstile antenna.
5. Specialized normal mode turnstile antennas called " superturnstile " or " batwing antennas " are used as television broadcasting antennas.
6. Dipoles may be used as standalone antennas themselves, but they are also employed as reflective array, turnstile antenna, log periodic antenna, and phased array.
7. Since the first turnstiles invented by Brown operated in this mode, the normal mode turnstile is occasionally called the " George Brown turnstile antenna ".
8. However, when that same turnstile antenna is used in the " axial mode " ( upwards, for the same horizontally-oriented structure ) its radiation is circularly polarized.
9. High gain antennas for helical, and turnstile antennas are used since satellites typically employ circular polarization which is not sensitive to the relative orientation of the transmitting and receiving antennas.
10. Data from the scientific instruments was transmitted to the ground by two MHz, and four flexible whips forming a turnstile antenna were fed by a 10 milliwatt transmitter operating on 108.00 MHz.
