There are a number of competing systems in use. Early adopters used C-band dishes several feet in diameter to receive analog microwave broadcasts, and later digital microwave broadcasts using the 3.7-4.2 GHz band. Today, although large C-band dishes can still receive some content, the 11.7-12.2 GHz is also used. Ku-band signals can be received using smaller dishes, often as small as under a meter (3 feet, 3 inches) in diameter, allowing FTA satellite to be picked up from smaller spaces such as apartment balconies (note, however, that these dishes are not quite as small as those commonly used for commercial services such as Dish Network, DirecTV, Bell ExpressVu, Shaw Direct, etc. Dishes intended for those services may not deliver an adequate signal on Ku-band). The European-developed DVB-S and DVB-S2 standards are the most commonly used broadcast methods, with analog transmissions almost completely discontinued as of mid-2014.
