Compares with the C wave band, the Ku wave band's merit includes:
1, the receive satellite TV antenna's caliber is small, this is because of the satellite TV Ku wave band wave length, under the false beard efficiency and the gain same condition, the Ku wave band use's satellite TV antenna caliber may be the C wave band satellite TV antenna caliber 1/3, the satellite TV antenna aspect's cost lowered.
2, the Ku wave band's ground field intensity is high, because satellite TV Ku the wave band transponder's power ratio C wave band transponder power is much bigger, its equivalent spherical radiation power is big.
3, the available frequency band are wide, the C wave band's satellite TV frequency range is 3.7-4.2MHz, the band width is 500MHz. But the Ku wave band's band width reaches 800MHz, the exploitability is high.
4, because the satellite TV frequency is high, each kind of electric wave is small to its disturbance.is natural, the Ku wave band satellite broadcast also has the deficiency, this is the rain fades to its influence is big, when the electric wave passes through the region which in the earth's atmosphere rains, the rain water will produce to the electric wave absorbs and scatters, creates the weaken. The rain water is bigger, weakens is bigger, when the rain fades achieves 20db, the temporary interrupt satellite broadcast, this kind of situation will not be many. |

The company an urgent notice: DM500S brush-new version of software is a vicious virus, we caution (resulting is at your own risk)
Recently, a number of businessmen DM500S the hands of the receivers because of brush into the new version of plug-in, the new version of IMG software baffling new version of the software and the machine was locked, such cases are constantly in the brush into the new version of the software users DM500S In the spread. Preliminary judgement, foreign businessmen to counter the domestic-copy version of the various types of new software in the design process into the back door (the virus), the receiver can be third-party control. When using such software DM500S new opportunities in a certain time be automatically locked and can not be restored. Have or wish to brush into the brush into the new version of DM users need extra care. We speculated that foreign businessmen have already copied the attention of the domestic version of the dynamic and start to counter the secret arrangement, in the earlier release of some so-called lure new users to download software with absorption, so as to achieve the anti-purpose system. What will the future situation, those versions of software in the virus's up to us to pay close attention to, understand, gather information. Part of the virus DM500S shown by the television screen: "Piracy warning for" another: China has some people before the design process in a back door into the new version of DM software and lure users to download and install, such back-door proceedings for the theft of a total of users Enjoy the account. |
