Europe
In Europe the frequencies used by DBS services are 10.7–12.75 GHz on two polarisations H (Horizontal) and V (Vertical). This range is divided into a "low band" with 10.7–11.7 GHz, and a "high band" with 11.7–12.75 GHz. This results in two frequency bands, each with a bandwidth of about 1 GHz, each with two possible polarizations. In the LNB they become down converted to 950–2150 MHz, which is the frequency range allocated for the satellite service on the coaxial cable between LNBF and receiver. Lower frequencies are allocated to cable and terrestrial TV, FM radio, etc. Only one of these frequency bands fits on the coaxial cable, so each of these bands needs a separate cable from the LNBF to a switching matrix or the receiver needs to select one of the 4 possibilities at a time.

Famous quotes containing the word europe:
“All the terrors of the French Republic, which held Austria in awe, were unable to command her diplomacy. But Napoleon sent to Vienna M. de Narbonne, one of the old noblesse, with the morals, manners, and name of that interest, saying, that it was indispensable to send to the old aristocracy of Europe men of the same connection, which, in fact, constitutes a sort of free- masonry. M. de Narbonne, in less than a fortnight, penetrated all the secrets of the imperial cabinet.”
—Ralph Waldo Emerson (1803–1882)
“When Paris sneezes, Europe catches cold.”
—Prince Metternich (1773–1859)
“Positively I sit here, and look at Europe sink, first one deck disappearing, then another, and the whole ship slowly plunging bow-down into the abyss; until the nightmare gets to be howling. The Roman Empire was a trifle to it.”
—Henry Brooks Adams (1838–1918)
