What is Free-To-Air Television?
Free-To-Air television involves the transmission of video and audio media content without charging the viewer(s) for the distribution of the signal. Free-To-Air TV channels provide their content without requesting for a subscription. However, viewers might require some sort of equipment before accessing this channels. Conventionally, they provide free entertainment content for audiences.
Free-To-Air TV should not be confused with Free-To-View. Free-To-Air television services are unencrypted and do not mandate a subscription, meaning that whoever has the necessary devices can watch. On the other hand, free to view (FTV) TV services do not also require a subscription to watch but are digitally encrypted and requires a conditional-access module and viewing card.

Why a Free-To-Air Television channel?
- Free to Watch: As implied by the name, free-to-air channels are free to watch. There are no subscriptions needed so viewers do not have to break the bank to watch their favorite channels.

How Free To Air Channels Work
Free-to-air television channels depend on four major things to work. They depend on the satellites, the signals, the dish and the receiver.
- Satellites: Free-To-Air television channels need a satellite for broadcasting. These satellites are free to access by having the right devices and frequency. They receive signals from broadcasting stations and reroute those signals back to the earth.
- Signals: The signals sent back by the satellites are unencrypted. It’s a raw format containing the video and audio for the free to air channel. Using a dish and configuring it to the right location will allow one to access the video and audio media.
- Dish: The dish is one of two equipment viewers need to intercept free to air television channel signals. The dish has a low-noise block downconverter (LNB) that it uses to strengthen the received signal and send to the receiver.
Receiver: The second of two equipment needed by viewers, the receiver is the end component of the free-to-air satellite tv configuration. It will extract individual channels from the satellite signal. Free-to-air tv channels do not require a specific receiver but the receiver should be compatible with the encoding of the signal – usually MPEG-2 or MPEG-4.
