Purchasing Satellite TV Equipment

Each day more people make the decision to get their television programming through a satellite. Satellite TV is increasing in popularity and that rise in popularity is expected to continue on into the future.

When it comes to satellite TV, there are many individuals who focus solely on the cost of getting the channels that they want. The price of a service is important, but so is the equipment that you plan on receiving that service with.

Satellite TV equipment can come from two different sources. It can come directly from a satellite TV provider or it can be purchased from another location. Where you get your satellite TV equipment will all depend on your personal preferences. Before you make a finial decision it is important that you educate yourself on the advantages and disadvantages of acquiring satellite TV equipment from certain locations.

Many satellite TV subscribers make the decision to get their equipment through their satellite provider. The biggest advantage of doing so is that the equipment can often be obtained for little or no cost. It is not uncommon for a provider to offer valuable deals and discounts on satellite receivers and dishes. This means that it is possible to become a customer without having to pay equipment fees.

The biggest disadvantage of getting satellite TV equipment through a provider is one that many individuals are not even aware of. The majority of satellite TV providers are not giving you their equipment; in fact, they are leasing it you. This means that if you decide to switch television providers you will have to return the equipment. This is something that many individuals do not have a problem with, but a problem may arise if the equipment is damaged. Damaged equipment or missing remotes may result in being charged the full retail price for each item.

The alternative to leasing satellite equipment from a satellite TV provider is to outright purchase the equipment. The most common place to purchase satellite equipment is from a traditional storefront retail location or online. Most traditional department stores and media stores carry a selection of satellite dishes and receivers.

There are a number of advantages to purchasing satellite equipment from a retail store. The biggest advantage is that the equipment is yours to keep. This means that you can take your dish and receiver with you on camping trips and other family outings without having to worry about being penalized should the equipment become damaged.

When a satellite TV provider leases equipment to their subscribers they tend to offer only the standard equipment. Buying the equipment from a retail store gives shoppers a larger selection to choose from.

Having a choice when it comes to purchasing satellite TV equipment is nice, but it can also result in errors. Not all satellite receivers are compatible with every satellite TV provider. That is why it is important to ensure that the two are compatible before paying for the equipment.

The price of satellite equipment is one of the most common reasons why individuals do not outright purchase their equipment. The average cost of a satellite dish and receiver, when purchased together, is between one hundred and two hundred dollars. It is important to note that the cost of a satellite dish and receiver will all depend on where the items are being purchased from.

Leasing satellite TV equipment and purchasing it both have their advantages and disadvantages. When deciding which is the best way to acquire satellite TV equipment you are encouraged to examine each advantage and disadvantage and then apply them to your situation.

Free Satellite TV

Free Satellite TV

Legality aside, any kind of Free Satellite TV offered by a business is looking for a profit. However, stealing channels is an unintelligent activity at the very least. Free Satellite TV is a bonus for paying the monthly service fees for at least one year. So how free is Free Satellite TV? If you sign up and pay a monthly service, the company is more than willing to offer a free installation, free DVR, free HDTV, free equipment and free channels.

What is Free Satellite TV?

Not all Free Satellite TV is the same. Different companies offer different policies. Generally speaking, more and more techniques are used to get people to sign up for a satellite TV service. Free Satellite TV is one of these things that people seem to think means getting a box from a company for free and then manipulating it into an all channel free service. Which is not only unwise, it's unnecessary. Free Satellite TV means getting free equipment, free installation, free to air channels and paying monthly service, just like everyone else. You can choose to pay for more channels other than the basic service, but that is your choice, and you pay only for what you are interested in. Channels you don't want, you don't get.

Free Satellite TV Equipment and Installation

Free Satellite TV equipment and installation usually include a DVR, HDTV and a technician going to your house with all the equipment and doing the setup for free. The DVR is a Digital Video Recorder, a box that records video feed from your Free Satellite TV to a digital storage space. Just like a hard drive on the computer, the DVR works as a virtual memory of video, related to the older analog VCR of the 80's and 90's. The HDTV is a High Definition Television unit that amplifies a video feed in such a way that the images, sounds and feelings coming from the TV are a far bolder experience. With HDTV the quality of a pin dropping from across the globe is as if from close up and in surround sound.

Free Satellite TV Channels

When we think about Free Satellite TV we also seem to think about channels. Free Satellite TV channels are those that are free to air channels from all over the globe. Public broadcasting in any country is free of charge with Free Satellite TV and when you add the number of public broadcasting stations up in the diverse developing English speaking countries around the world, that comes to a whole lot of educational programming for one monthly signature in a basic package. And if you are thinking about the family, there is no better set of family channels than the Free Satellite TV channels.

Free Satellite TV is about paying a monthly service and the bonuses that come with a basic monthly package. Free Satellite TV comes with free installation, free equipment, free channels that include radio, public and educational programs from all over the world. So how free is Free Satellite TV?

"Unless you want more than a basic package, it will cost a monthly signature to your local Dish Network for a minimum of one year to get Free Satellite TV."

Satellite TV: A Worthwhile Investment

Millions of people have signed up for satellite TV. So, what's so fantastic about satellite TV that makes hundreds of new subscribers sign up every day? You will be pleasantly surprised. Not only does satellite TV provide great programming options, but there are myriad other benefits to be derived. Let's examine some of these.

First, the idea that satellite TV can provide you with some 500 viewing channels cannot be passed over. Many individuals love the fact that satellite TV offers them the ability to access their favorite movie channels, sports channels and specialty channels. Not only do satellite TV subscribers get access to great stations like HBO, Cinemax, Showtime, Starz, CNN, ESPN and more, but they also get to subscribe to all of the variants of such stations.

The pay-per-view options offered are equally appealing. Viewers can order one-time specials or watch special sports programming if they so choose. Also, if a movie they have been waiting to see becomes available via pay-per-view options, viewers can save quite a bit of money by ordering it that way versus visiting the local cinema. Likewise, when individuals have satellite TV - with the diversity of programming available, fewer visits to the local video dealer are required.

Along with the ability to access outstanding channels, satellite TV is putting control back into the hands of parents across the nation. Parents can now preprogram their satellite television box to block out shows that they don't want their children watching. This, in addition to the educational television shows on offer from providers like Dish network and DirecTV, promises parents utter control of their children's viewing habits. It is truly a blessing when parents do not have to worry over whether or not their children are watching something they shouldn't be, when parents are otherwise occupied or the children are not in their immediate care.

Another perk gained from satellite TV subscription is the access to various music channels. People can enjoy New Age selections, pop rock, heavy metal or classic rock selections and oldies from a variety of stations that offer different music. Also, special weather stations and even games can be enjoyed through satellite TV subscriptions. Children can enjoy video gaming channels and parents can enjoy the myriad television selections provided to them. What's more, with an easy to use remote control provided with your subscription, programming your preferences couldn't be an easier process.

Considering the benefits derived from satellite television, the price paid for monthly service parallels such benefits. You get more for your money with satellite TV as you pay just about as much for it as you would pay for regular cable services. Thus, with all of the additional benefits you receive, you will be making your hard earned money work for you. In the end, if you don't subscribe for satellite TV, you'll never know what you are missing out on.

How Satellite TV Works

Digital high definition satellite television is increasing in popularity, with Dish Network recently reporting crossing the 12 million subscriber threshold and growing, and there are probably more uninformed as to actual workings of satellite TV than informed. How does Dish Network make television programming so realistic in image and sound?

Dish Network, owned and operated by EchoStar Communications, receives digital satellite signals from their fleet of nine satellites. Plans are underway at present for EchoStar to launch their tenth satellite this month - February - increasing their ability to bring you more and better entertainment. Communications/television satellites orbit synchronously at an elevation of about 22,000 miles above the Earth remaining over certain land masses/areas so that a receiver dish can remain stationary on the side of a home or in a yard. The advanced research and growth of Dish Network is directly attributed to their continued enhancements in the area of home entertainment programming.

Dish Network obtains select programming from providers like Life Time, HBO, CNN, ESPN, Cinemax, Showtime, STARZ, and other sources. These providers, also known as 'uplink' sites initially beam their signals to the satellites. Dish Network's, whose broadcast facility is located in Colorado, satellites then digitize the signaling for quality, encrypt the signals, and then transmit a digital high definition rebroadcast to installed receivers in subscriber homes providing the best in home entertainment services. Each satellite has what is called a target area or 'footprint', and programming from a given satellite can only be received within that particular target area or 'footprint'. The 1980's and 1990's dish receivers were huge, some being about 10 feet in diameter, but now it is completely portable so it is easy to take your receiver with you as you travel in recreational vehicles or boats - just place your dish facing a Southern sky and signals are easily received.

This process allows Dish Network to deliver digital high definition and standard satellite services all over the world and to offer subscribers over 256 channels of quality programming plus 50 channels of Sirius music in CD quality clarity. Dish Network offers the most complete and diverse packages available with premium movie channels, 500 commercial-free movies each month, excellent sports channels, interactive gaming with local and national weather and traffic updates, multi-cultural international programming, educational channels, VOOM high definition channels, and children's and adult channels. A Parental Lock feature is included for absolute control in family viewing. Dish Network offers free equipment and installation and specified services for a limited time. As a gift to first-time subscribers, Dish Network includes a Digital Video Recorder - free - to further enhance viewing enjoyment. The DVR allows you to digitally record and store up to 100 hours of programming in 100 percent digital high definition imaging and sound. This lets the viewer record, fast-forward, rewind, and pause - even stopping live broadcasting for annoying interruptions - and then resuming with no problems. You can create your own instant replays with your DVR as well as a library of your favorite movies, sports events, or music.

Click on Dish Network now for complete information on packages and pricing. Comparison-shopping will confirm that you can have the best and most for about the same amount you are now paying for average television programming. Ordering is easy - online or by telephone. A friendly Dish Network representative will answer any questions, take your order, and schedule installation for a time that fits with your busy schedule.

Now you are informed as to how your new Dish Network digital satellite television home entertainment system operates.

The Future Of Dish Network And Satellite TV

If you have Dish Network or thinking about getting it or another satellite TV service, it?s good to know what the future holds for satellite TV. So, here?s a glimpse into the future.

This article may be considered science fiction, just like Arthur C. Clark once had a scientific vision about 3 satellites orbiting the earth in geostationary orbits to make global communications possible. Everything in this article is merely a scientific vision and an extrapolation of current technologies into the future.

What would be the future of Satellite TV? That may seem to be a difficult question, but extrapolating what we know about the past into the future and some educated guesses, we may very well end up with a reasonable picture of what the future of satellite TV looks like. The future of satellite TV will be guided by these properties:

1. Receive and Transmit
2. Equipment Size and Costs
3. Satellite Capacity and Coverage
4. Antenna Size
5. New Technologies

1 Receive and Transmit

What would be possible if you could not only receive, but also transmit? And in the same bandwidth as you receive? That would change the whole world. It is possible now to use the satellite for Internet purposes, but in a very simple and inefficient way. You receive via satellite, but transmit via phone. Upload capacity is completely limited by the dial up connection.

The idea of being able to transmit to a satellite from your home is new and will probably one day be reality. At the moment companies can use satellites to connect offices all over the country via satellite. Bandwidth is limited, or very expensive. Another problem for home use is the size of the satellite dish. At least 4 foot for small bandwidth and up to 10 feet or even more for higher bandwidths. In point 3 this bandwidth issue is explained in more detail.

2 Equipment Size and Costs

Your Dish Network or Satellite TV equipment at home may seem small, but it is small because all it has to do is receive. Transmitting requires different equipment. Not so much in the house, but on the roof at the antenna there is need for a relative big transmitter. Also these are still pretty expensive and for domestic use just not affordable.

In the future this will change. Equipment will get smaller, and cheaper. Eventually when satellites are able to relay much more data than now (see point 3), having 10.000.000 transmitters on the ground won't be a problem.

3 Satellite Capacity and Coverage

This will always be the bottle neck of satellites; how much data can they relay and how small an area can they cover. A satellite has multiple dishes and each dish can cover a part of the earth; small parts like just one state or big parts like the whole continental United States.

In the future satellites will be able to relay much more data, and cover much smaller areas. Especially the smaller coverage areas will be important. Having full capacity available for just a small area means higher bandwidth available for a small amount of people. Especially in urban areas it will be great to have a satellite cover just one neighborhood.

4 Antenna Size

This is a very important issue. Small antennas of 18 inches already exist and are used by satellite TV providers such as Dish Network, but these can receive only. The opening angle of an antenna like this is too big to get enough signal power to reach the satellite. In the future however, antennas will get better and eventually small antennas can be used to transmit to the satellite.

5 New Technologies

This will be the really interesting part. New technologies may open up possibilities that are never heard of before.

Imagine watching a movie in 3D, you sitting on your couch but watching a show as if you are in the audience when the TV show was recorded. You're not really having a TV at home anymore, but a 3D entertainment room. (for those of you who like StarTrek, a not so strange idea). Normal Satellite TV will still be available of course.

In the future Satellite TV will open up so many possibilities that it is hard to imagine what our lives will be like in 30, or even just 20 years from now. To give an idea of how fast things are going. 50 years ago, there was nothing in space that was made by humans. Now there are even satellite graveyards (specific orbits where obsolete satellites are "parked"). The possibilities of satellite TV technology are growing faster every year. What took 10 years to develop 30 years ago is now done in 2 years.

Dish Network and Satellite TV is one of the driving forces for satellite technologies because the need to please million of subscribers is much stronger than the need to please the relative limited needs of communications for commercial purposes. The future of satellite TV is so bright, that a supernova would pale in comparison!

Satellite TV Systems -- Which One is Best?

Satellite TV System

A satellite TV system consists of a dish that captures the TV signal broadcast from a satellite, and a receiver that amplifies the signal and sends it to a television.

Less than 10 years ago, satellite TV systems consisted of a huge satellite dish, about the size of a flying saucer, and an array of black boxes that required an electronic technician to set up. Not only that, they were expensive, costing anywhere from $2,000 to $10,000.

We've come a long way since then. Now, satellite dishes are the size of a large Frizbee, the receiver is the size of a notebook, and using the system is as easy as operating a microwave.

And the best news of all is that today's systems won't cost you a penny. Thanks to the ongoing competition between satellite TV dealers, they'll give you a complete satellite TV system for free when you subscribe to their satellite TV service.

Benefits of a Satellite TV System

Here are the benefits of having a satellite TV system:

* You have the option of viewing up to 256 channels of programming.

* Satellite TV is broadcast in an all-digital format for the clearest picture and sound available. * Satellite TV systems include DVR (digital video recording) so you can record your favorite shows.

* You can get HD (high definition) receivers that allow you to watch your shows in HD format.

* Satellite TV is the more reliable than cable or over-the-air TV, with less blackouts and fewer picture problems.

* Customer service is available 24 hours a day, seven days a week.

How a Satellite TV Antenna Works

Practically all broadcast systems use antennas to transmit and receive radio signals. These antennas are based on single metal pole to which the carrier signal is sent through a cable. First lets talk about how this most simple type of antenna works:

Pole Antenna

A Pole antenna basically consists of one metal pole that transmits it signals around it as if it was the center of a sphere. In all directions the transmitted signal has the same power. The length of the antenna is determined by the frequency of the transmitted signal.

Radio waves, like light waves, always travel at the same speed, which is about 186.000 miles (300.000 km) per second. One wave length is determined by the frequency of the signal by the following formula:

Wavelength = speed of light / frequency

This results in higher frequencies having shorter wavelengths. A pole antenna doesnt have to have the length of a complete antenna but can also have a length of about , 1/8, or 1/16 of the wave length. This is done mostly for practical purposes (shorter antennas). Wave lengths for pole antennas can go as high as 1 to 2 Giga Hertz. A cell phone for instance works at frequencies of 950 Mega Hertz which is almost 1 Giga Hertz.

Satellite TV or Parabolic Antenna

A satellite TV Antenna or parabolic antenna works on the same principle. The frequencies used by satellite transmissions are of much higher frequencies; 2 Giga Hertz or higher. Wavelengths get so short at these frequencies that it is not possible anymore to transmit using a pole antenna and transmit in all directions. The power needed would be very high because high frequencies are subject to much more resistance from the atmosphere.

Bundling all the transmitted power into a beam improves the power transmitted in one direction by a huge factor. Depending on the distance between the transmitter and the receiver the amplification compared to a normal pole antenna can be as high as 40 to 50 dB (which is as much as 10.000 to 100.000 times amplification).

In reality the beam is not completely straight, but gets wider over the distance. The angle is small, but in case of an antenna on a satellite that transmits all over the USA the angle is actually a little bigger so that the whole USA is covered.

The antenna at your roof or in your garden is pointed at the satellite and receives the signal and does the same thing; it bundles the radio waves into a point, thus amplifying the radio signal with 40 to 50 dB. (see illustration below).

Amplification in the whole path is extremely big. The transmitting antenna amplifies, the receiving antenna amplifies, the transmitter it self amplifies, and the receiver itself also amplifies the signal. A total amplification of over 120 dB (over 1.000.000.000.000 times) is necessary because the atmosphere and also the long distance just decrease the signal power a lot.
