Why Choose Sirius Satellite Radio?

Your choices in listening options are steadily growing. With traditional "terrestrial" radio options, XM and Sirius, you have a number of different choices. Why choose one over the other, though? What does Sirius offer to set them apart from their competition? Let's look at what is available.

Terrestrial Radio: What do you get with terrestrial radio? Local programming with local news, a variety of music choices and talk radio is usual. You also get poor signal if you are too far away from the signal source, terrible radio programs and commercials. Lots of commercials! Other than that, there really isn't all that much that this form of radio has to offer. In fact, many terrestrial radio stations are spending more and more money on Internet radio applications in an attempt to boost their popularity.

XM Radio: XM is a brand of satellite radio; that is, they provide the same service all over the US, whether you're in Bangor Maine or L.A. They offer an enormous amount of programming, mostly commercial free (some stations do have commercials). They also offer a number of ways in which you can tune in, from built in radios in new vehicles to personal listening devices and home listening devices.

XM satellite tv some programming that you can only get through them, though these are not as popular as those offered through Sirius. In addition, XM does boast more stations than Sirius does.

Sirius radio has many similarities to XM Radio. They are both satellite radio providers, they both offer coast to coast programming and they both work in your vehicle. That is the extent of the similarities between these two companies. Sirius has far more original (exclusive) programming than XM does. Witness the incredible popularity of both the Howard Stern Show and NASCAR radio.

There are also a number of other popular options to be found within this radio provider. Sirius offers more ways to listen than XM does, as well. Sirius boasts a large line of quality devices, from simple car kits to units designed to work in both your car and your home, personal music devices that can wirelessly transmit to your car's stereo and home tuners that make other systems pale in comparison. Let's not forget about the sleek Stiletto 2 which doubles as an MP3 player and allows you to listen to satellite radio like a walk-man wherever you have access to Wi-Fi.

Regardless of the music provider that you choose, there will be a cost. With Sirius and XM radio, the cost comes in the form of a subscription. With terrestrial radio, the cost comes in the form of commercials, poor programming and a lack of signal strength. With satellite radio, at least the cost you pay offers you coast to coast performance and high quality programs. Listening to the type of music, talk radio, news or sports coverage that you want, when you want to, is the single biggest reason to switch.

Sirius Radio offers the best options, both for listening enjoyment and for listening methods. With them, you can find the best system configuration for your needs, whether it be solely in-car or a combination of different places.

Sirius provides a new resource for finding that perfect new artist. Whit commercial free programming, you never miss out on hearing the latest artists.

Satellite TV - What is it and How Does it Work

You may have already seen several households all around the United States, especially in rural areas, with compact dishes hovering on their rooftops. That means these households have satellite TV and are enjoying the services of satellite television companies.

Satellite TV is another way of delivering television programming to the viewers. It is a lot similar to broadcast television. Both of them transmit programming with the use of radio signals. However, there are some limitations to broadcast television.

Broadcast vs. Satellite

Broadcast stations make use of a powerful antenna to transmit radio waves to the surrounding area within a specific range. The viewers of broadcast TV have a smaller antenna to pick up these signals transmitted by the station.

However, the smaller antenna should be in the direct line of sight of the station's antenna to be able to receive a good signal. The signal received is also often distorted unless the receiver is very near the transmitting station.

Satellite TV companies, on the other hand, have a solution to the range and distortion problems of broadcast TV. It transmits broadcast signals through satellites orbiting the Earth. Since these satellites are situated high in the sky, there are definitely more receivers in the line of sight of the transmitted signal.

How It Works?

The systems make use of satellite dishes which are specialized antennas to transmit and receive radio signals. The communication satellites used in a TV are launched into space at about 37,000 km above the Earth's surface at the speed of around 11,000 kph. With this speed and altitude, the satellite can keep pace with the Earth's movement exactly which means it revolves around the Earth once every 24 hours.

The satellites are also in geosynchronous orbit which means they stay in a single location in the sky relative to the earth. Thus, the dish needs to be directed at the satellite once as long as everything works fine.

Satellite television starts with a transmitting antenna situated at an uplink facility. The uplink dishes are directed at the satellite to transmit signals to as much as 9 to 12 meters in diameter. The bigger the diameter, the more improved the reception will be. The signal is transmitted to transponders on-board the satellite, which retransmit the signal back to the Earth using a different frequency.

The signal is quite weak due to travel in space. However, this signal, once collected by the parabolic dish, is down-converted to a lower frequency band then amplified using a low-noise block down-converter, or LNB.

Types of Distribution

There are two primary kinds of satellite television distribution, namely television receive-only (TVRO) and direct broadcast satellite (DBS).

Television receive-only is a satellite TV reception device based on open standards satellite tv This type is often referred to as the big dish TV. TVRO systems more often use larger dishes since a C-band setup is more common to satellite tv of this system, although it is designed to receive signals both from C-band and K u-band signals.

Direct broadband satellite TV is also known as "direct to home". DBS systems are also referred to as the "minidish" systems as it uses small dish that we commonly see around. This system uses the upper portion of the K u-band.

Satellite TV is getting more popular nowadays. It can be a good alternative to the regular broadcast TV or the more common cable TV.
