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:
“...I think the Americans are the only people who have good beds. I consider the American bedroom unparalleled for freshness, comfort, and cleanliness. It is worth going all over Europe in order to come home to one’s own bed.”
—M. E. W. Sherwood (1826–1903)
“You can always tell a Midwestern couple in Europe because they will be standing in the middle of a busy intersection looking at a wind-blown map and arguing over which way is west. European cities, with their wandering streets and undisciplined alleys, drive Midwesterners practically insane.”
—Bill Bryson (b. 1951)
“The confrontation between America and Europe reveals not so much a rapprochement as a distortion, an unbridgeable rift. There isn’t just a gap between us, but a whole chasm of modernity.”
—Jean Baudrillard (b. 1929)
