FTA Sources

• FTA or free-to-air is a type of TV that does not require a subscription. FTA signals are broadcast without encryption and can be legally viewed by anyone with the proper equipment.
  
  Free to air is broadcast from satellites in orbit. Different satellites broadcast separate programming. Most FTA programs are cultural or educational in nature and offered as a public service.
  
  Because these satellites can be received from nearly any location, FTA television is often accessible even in areas where traditional and cable TV is unavailable.
  
  

FTA Dishes

• There are two types of satellite dishes that can be used to receive FTA: C-Band and Ku. Both of these types are widely available and are fairly inexpensive. C-Band uses larger dishes and is an older technology, while Ku band dishes are newer and smaller.
  
  FTA satellite dishes cannot transmit. They are designed to receive only. The shape of the dish focuses distant television signals and tunes in the broadcast. Usually, an FTA dish is aimed at one satellite. Dishes can also be motorized to aim at multiple sources when needed.
  
  

FTA Receivers

• An FTA receiver decodes the satellite information. This is similar to a standard cable box. A coaxial cable connects the dish to the receiver, which is in turn plugged into the TV.
  
  FTA receivers use software to scan and find available satellite broadcasts. These are assigned to different channels, which can be easily switched. Once channels are set, the system operates from a remote. Viewers can tune into a variety of programs from the comfort of the living room, with no subscription charge required.
