There are a number
of competing systems in use, with early adopters having used C-band satellite
dishes of several feet in diameter to receive signals which were originally
analogue microwaves, and then digital microwave using the 3.9-4.2 GHz band.
Today, in the 11.7-12.2 GHz Ku band, which enables the use of under one-meter
dishes, with most often the DVB-S standard, FTA can be used from apartment

Most of these signals are carried by US satellites. There is little or no free Canadian DVB-S content available to users of medium-size dishes as much of the available Ku-band satellite bandwidth is occupied by pay-TV operators Shaw Direct and Bell TV, although the large style dish (over 3 feet/90 cm) does have a few choices. FTA signals may be scattered across multiple satellites, requiring a motor or multiple LNBs to receive everything.
The largest groups of end-users for Ku-band free-to-air signals were initially the ethnic-language communities, as often free ethnic-language programming would be sponsored by Multilingual American Communities and their broadcasters. Depending on language and origin of the individual signals, North American ethnic-language TV is a mix of pay-TV, free-to-air and DBS operations. Today, many American broadcasters send a multitude of programming channels in many languages, spanning many new channels, so they can get National support, which ultimately leads to carriage by cable systems, to additionally support the high costs of broadcasting signals in this way.
Nonetheless, free-to-air satellite TV is a viable addition to any home video system, not only for the reception of specialized content but also for use in locations where terrestrial ATSC over-the-air reception is incomplete and additional channels are desired.
