Effective Isotropic Radiated Power is the apparent power transmitted towards the receiver, if it is assumed that the signal is radiated equally in all directions, such as a spherical wave emanating from a point source; in other words, the arithmetic product of the power supplied to an antenna and its gain. EIRP = G *…
There are two standards for DTH internationally: European standard DVB-S and American standard DigiCipher. But the DVB standard is gradually used widely throughout the world. The Dish Network of American DTH company newly grew also adopts this DVB standard. DTH system consists of 6 parts Headend system Headend system is mainly composed of Video Audio…
Receiver controls LNB via coaxial cable. And the satellite signal reflected from antenna will be transmitted to satellite receiver and demodulate programs after first frequency conversion through LNB. Local frequency: Every LNB has fixed LO, C-band is 5150MHz, In Ku-band, set the LO according to the different frequency. Among 10.7-11.7G, the LO is9.75G; while among…
We stipulated the direction here all refers to the direction seen when we face to the Satellite Dish. Satellite Dish C-band single polarization separated LNB polarization angle setting We stipulated the F interface of this kind of LNB is the direction marked 0 scales. The Satellite Dish polarization angle of horizontal signal when receiving different…
Quick and accurate adjusting method for Asian 3S digital programs 1. Assemble the 1.5 antenna according to the assembly drawing, each connection point should be fastened, the foundation should be leveled, or it will affect the reception effect. 2. When assembling the LNB, block the top of feed plate to the “38” line on LNB.…
