The first satellite dishes for television were large dishes of six to 12 ft. in diameter. These started to pop up in the backyards all over the U.S. in the late '70s and early '80s. This first satellite system came to be known as TVRO (television Receive Only) and is still a thriving industry today with these larger dishes mostly seen on large commercial buildings such as hotels and office complexes. TVRO is described by a other terms such as Big Dish TV, B U D (Big Ugly Dish), C band satellite TV, and Full View. TVRO or C- band satellite dishes also have the ability to move their aim towards different and satellites. In the continental United States TVRO satellites are able to receive up to 20 C band satellites. Now they also can be upgraded to receive free or unscrambled programming from the more modern and superior K U band frequency satellites. TVRO systems are more expensive and difficult to install and require regular maintenance. However, they have the advantage of a large amount and variety of programming including free programming and cable programs that are not available on regular satellite tv and cable. The two types of channels that one can pick up with a TVRO systems are scrambled or subscription services and free channels.
Today almost everyone uses the more modern and superior K U band frequency satellites that use subscription services. These satellites operate in the highKu frequency range of 12GHz to 14GHz compared to the lower C band frequency in the 3.4-gigahertz (GHz) to 7-GHz frequency range. This frequency makes it possible for signals to be compressed into 30:1 MPEG-2 compressed video signals which allows far more channels to be squeezed through without damaging digital clarity so that there is a large number of up to 200 channels from one satellite. Also, because a number of satellites can be received by one dish, providers can offer 500 or more channels to your satellite dish. This K U frequency microwave also made it possible to have High Definition Television.
TVRO satellites can be upgraded to receive free or unscrambled programming from these more modern and superior K U band frequency satellites. The vast majority of what one can then pick up from the K U band is free although there are also some scrambled signals that one can pick up with a descrambler. Many of the modern satellite receivers already have the ability to receive K U band signals. However, if an upgrade is required it only involves some small modification to the feed and LNB just above the center of the dish.
To view scrambled subscription services you need a descrambler which in today's modern receivers is part of the receiver. Usually it's easily removed by simply sliding out a metal plate that is covered over it. For more details on this click here. All one needs to do is contact a provider by phone and while you're still talking on the phone after you've paid the signal is sent that descrambles and you're already watching. You can contact providers by looking in satellite TV magazines, doing a search on the Internet, or just going to blanked out unpaid satellite channels where there's often the advertising of various providers.
There's a tremendous variety of free channels or what are also known as unscrambled channels or channels in the clear that you can receive on TVRO systems. There's free special religious programing, News, music, old movies, educational, foreign-language programming, and many other unusual programs. Some of these programs are regularly scheduled and usually are programs of special interest in fields such as science or art. Feeds are programs that are used by networks or other programming providers to send shows, events or news to their affiliates and can be scheduled or non scheduled. Its really interesting to pick up unscrambled unedited news feeds used by program providers or networks to send reports out from the field to their main operations center. It's a real eye opener to view these unedited news feeds and find out what the news does not want to report. Some of these news feeds are live and others are fed to a place where they will be edited for later use. With TVRO Sports buffs and fans love to pick up, for example, a game being played in the eastern United States which is being beamed unscrambled over to- let's say- San Francisco, to carry on a television station there. Added to all these benefits, there's an extensive variety of free radio stations that one can tune into from all over North America-you can't beat that!
