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.

“The Afrocentric exploration of the black past only scratches the surface. A full examination of the ancestry of those who are referred to in the newspapers as blacks and African Americans must include Europe and Native America.”
—Ishmael Reed (b. 1938)
“The people of Western Europe are facing this summer a series of tragic dilemmas. Of the hopes that dazzled the last twenty years that some political movement might tend to the betterment of the human lot, little remains above ground but the tattered slogans of the past.”
—John Dos Passos (1896–1970)
“Of one thing I can assure you with comparative certainty, whoever wins, Europe will be economically ruined. This war is America’s great opportunity.”
