Satellite Television

If the tv signal is coming to your house by a tv antenna on the roof, then a special very wide band radio signal is used. Your classic tv tuner can pick one tv channel out of all the different channels that are in the air. Same idea is used for satellite dishes except the signal has been converted to be a very high microwave frequency, and you need a satellite receiver to convert the microwve signals back to regular tv tuner signals.

If you have cable tv, the similar tv signals come to your house, only they get to your tv through a wire and there is no antenna used.

The signal for a single channel is about 4-5 megahertz wide. That's like an FM radio station channel that goes all the way from 100 to 105 on the FM dial, for a single channel. You could only squeeze 3 or 4 channels in to whole FM radio band.

The tv pictures are sent one at a time, about 30 per second, so it looks like smooth motion.

To visualize the structure of a tv signal: At about 100 mhz would be special pulses and codes to start the picture. From 100.5 to 104.5 would be the thousand of color dots you see on the picture tube, and the briteness of each dot. Then at 104.5 you would find the soundtrack which very much like an FM radio station, infact you can listen to the audio without watching the picture, on some radios.

Every second many slightly different pictures are flashed before your eyes on the screens and all you see is the smooth tv motion pictures.

Hope this helps a little.

Sky is the British satellite broadcast platform that is normally subscription based. However, a few channels are free to air and therefore, a Sky receiver will continue to receive those channels without the subscription being paid.

As an alternative, Freesat is a completely free service for the UK and requires no subscription. Compared to the Sky paid service, the number of channels is limited but is still a worthwhile range of programmes.

You will either need a composite(not component) cable or a HDMI cable. I think you can use S-Video but S-Video doesn't compare to HDMI or composite.

The universal remote control code for a Proline Digi Box can vary depending on the brand of the universal remote. Common codes used for Proline devices include 0802, 0092, and 0032, but it's best to consult the user manual of your specific universal remote for the most accurate codes. Additionally, you can perform a code search function on the remote to find the correct code if the listed ones do not work.

Microwaves can be used for satellite TV communications because they can travel long distances with minimal attenuation and penetrate the Earth's atmosphere effectively, allowing signals to be transmitted from satellites in orbit to ground receivers. In contrast, terrestrial TV often uses lower frequency signals that are better suited for covering shorter distances and penetrating buildings. Additionally, terrestrial TV relies on a network of ground-based transmitters that are optimized for local broadcast rather than long-range transmission like satellites. Thus, the characteristics of microwaves make them ideal for satellite communication, while terrestrial systems utilize different frequencies.

Satellite dishes are parabolic in shape to efficiently focus incoming satellite signals onto a single point, known as the feed horn, located at the dish's focal point. This design maximizes signal strength and quality by collecting and directing the signals from a broad area into the receiver. The curvature of the dish ensures that signals from satellites, which are positioned high above Earth, are captured effectively. Additionally, the parabolic shape minimizes interference and enhances overall performance.

To set up a satellite television system, you will need the following equipment: * A Satellite Dish: This is a parabolic reflector which can be made of solid aluminum, perforated aluminum or wire mesh. It is by far the most visible part of a satellite system. The dish can be small, such as a KU-band dish which is 3-4 feet, average that is 7-12 feet, or the big commercial C-band dish which is 16-20 feet. The 10 feet size dish is the most commonly used one. The dish helps to relay the microwave signals coming from the satellites. * A Mount: A mount is set on a 3-inch pipe which is in turn set in the ground with concrete. The most popular type of dish mount is the Polar Mount, which is so called as it is developed to coincide with the earth

CBS Sports Network is on channel 158 with Dish. It is available with our Top 200 and above programming package, Dish America Silver and above, and Dish Family programming packages. Thanks.
