What Is Free To Air Satellite Tv

What is​ Free To Air Satellite TV?
Free to​ air satellite TV is​ a​ term used in​ describing satellite signals that you can legally capture with your television, even without a​ subscription .​
Unlike ordinary programming, a​ free to​ air satellite TV does not encrypt the​ signals .​
Instead, it​ uses MPEG-2 to​ encode the​ received signals.
Free to​ air satellite programming transmits using C-band (a frequency allocation used for​ a​ communications satellite that uses 5.925 to​ 6.425 GHz for​ uplinks and​ 3.7 to​ 4.2 GHz for​ downlinks) .​
However, modern free-to-air satellite TVs use Ku-Band programming that uses frequencies of​ 14 to​ 14.5 GHz for​ uplinks and​ around 11.7 to​ 12.7 GHz for​ downlinks .​
Uplinks are signal paths from earth stations going to​ a​ satellite .​
On the​ other hand, downlinks are signal paths from a​ particular satellite going to​ earth.
Free to​ air satellite TVs enable you to​ pick up different unencrypted broadcasts via any appropriate receiver .​
You should not confuse free to​ air satellite TV with FTV (or free-to-view) because FTV programming also comes without charge, but is​ encrypted .​
This means that having free-to-view programming on your television can restrict various broadcasts, depending on your geographic location.
How to​ Receive Free to​ Air Satellite TV Channels
Unlike ordinary satellite TV programming that needs subscriptions from DirecTV, Dish Network or​ other satellite TV broadcast providers, free to​ air satellite TV channels can be received even without paying a​ monthly fee to​ broadcast providers .​
Free-to-air programming is​ commonly used for​ international broadcasting.
In order to​ receive free-to-air satellite TV channels, you need to​ have a​ satellite dish (either a​ K-band or​ C-band), a​ free-to-air satellite receiver or​ a​ suitable PC card, an​ LNBF (low noise block with an​ integrated feedhorn) and​ an​ antenna motor, if​ you desire to​ capture channels from different satellites, instead of​ through only one satellite.
Earlier systems used C-band satellite dishes, which are several feet in​ diameter, in​ receiving signals .​
However, modern dishes use Ku-band and​ other dishes that are under one meter for​ international DVB (or digital video broadcasting) standards .​
U.S .​
satellites carry most signals from international DVB .​
Because of​ this, free to​ air satellite TV channels may be scattered within multiple satellites .​
When this happens, you need multiple low noise blocks in​ order to​ receive all the​ channels you wish.
Free to​ air satellite TV, regardless of​ the​ type of​ dish programming used, is​ a​ great alternative when you are located in​ areas with poor over-the-air reception.
