The dish had to be pointed directly at the satellite, with nothing blocking the signal. Weaker signals required larger dishes. [4] [5] [6] The dishes worked by receiving a low-power C-Band (3.7–4.2 GHz) frequency-modulated analog signal directly from the original distribution satellite – the same signal received by cable television headends.
The set-top box selects the channel desired by the user by filtering that channel from the multiple channels received from the satellite, converts the signal to a lower intermediate frequency, decrypts the encrypted signal, demodulates the radio signal and sends the resulting video signal to the television through a cable.

A satellite minidish. This is a list of the free-to-air channels that are currently available via satellite from SES Astra satellites (Astra 2E/2F/2G) at orbital position 28.2 °E, serving Ireland and the United Kingdom. Sky and Freesat use these satellites to deliver their channels. If one was to change providers between Sky and Freesat, one ...
Home2US Communications Inc. also offers several ethnic channels on SES 1 at 101° W, as well as other free and pay-TV channels. Many religious broadcasters reach the DTH and distribution markets with unencrypted DVB-S television and radio channels on Galaxy 19. These channels are available as part of the Glorystar Satellite Service.
FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by K200AA.; TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel E4A or channel IC, but at lower volume than wideband FM broadcast stations, because of the lower deviation.
Entertainment includes more than 90 live TV channels that include ESPN, Nickelodeon and HGTV plus more than 60,000 on-demand shows and movies as well as your local channels.
Mobile reception of some stations will still be more difficult, because 18 UHF channels in the U.S. have been removed from TV service, forcing some broadcasters to stay on VHF. This band requires larger antennas for reception, and is more prone to electromagnetic interference from engines and rapidly changing multipath conditions.
Average signal levels, taken at the same height, varied by up to 6 dB, and for individual frequencies by up to 14 dB. In RF reception terms these figures are huge differences. Although carriers and broadcasters attempt to design their networks to eliminate dead zones , no network is perfect, so coverage breaks within the general coverage areas ...
