Yes, that's why when you see them on buildings, they're either on the roofs or pointing towards an open sky. Weather has a factor too. Heavy cloud coverage can slow info down, but they are getting better at it.

From the Satellite TV Providers, they transmit satellite tv signals by using a device that converts a digital signal to analog signal. This box sends it to the satellite dish of the provider to the satellite. When a subscriber switch channel, the satellite dish installed to his receiver then requests a signal from the satellite. The satellite receives the signal from the subscribers satellite dish. The satellite sends the analog signal which came from the provider the requesting satellite dish. The receiver converts this analog signal to digital signal so that the signal can be viewed to the television which is connected from the receiver.

The weather doesn't have any effect in satellite TV signal. The reason why people are blaming the weather regarding signal interference is because the satellite dish is not in a secured place. If the satellite dish is not in a secured area, these may be the effect: Strong wind can blow away the satellite dish. A blizzard can interfere signal if the dish is filled with snow. Strong rain can also move the satellite dish from its location where it is pointed. Strong heat can damage the satellite dish As a user of a satellite dish. It is advisable to secure the satellite dish.

satellite tv providers converts the signal using a modulator and demodulator. it then will be sent to the satellite using a satellite dish. the satellite dish installed in your house receives the signal from the satellite then converts the analog signal to digital signal by the receiver. once it's already a digital signal you can view it now to your television set.

A satellite dish relies on signals from a satellite to operate. As the signal must pass through the atmosphere, weather conditions can sometimes adversely affect the signal strength. Snow, rain, dust are all capable of disrupting the reception of many small satellite dishes. The bigger the dish, the less risk of signal drop out.

Certain dishes are used with certain receivers. The dish has LNBs that pickup the signal from the satellite and transmits that signal to the receiver using a coax cable. The receiver decodes that signal to give you the picture. When installing the dish, you need to align the dish to receive the signal from the satellites. Your location or zip code dictates the elevation, azimuth, and skew to set the dish. From the LNB, a coax cable is run to the receiver. If more than 1 satellite is used, either 2 coax cables are run or a separator, using 1 coax cable from the dish,is used to split the satellite signal at the receiver.

The DSTV decoder connects to a Satellite Dish on the top of your house. That dish receives a digital satellite television (DSTV) signal. Your decoder then decodes this signal and outputs it into your TV.

The correct signal for satellite TV is determined by the direction the satellite dish is pointed. DirecTV and Dish Network signals come out of the Southern sky from the direction directly above Texas. Many other satellites orbit the earth and send out audio and video signals of all different types and formats. Simply put, a satellite dish is like a catchers mitt and will catch any signal coming from the satellite it is aimed towards. The signal received will need to be properly matched with the in house receivers and equipment in order to work properly. For example, if a Dish Network dish is aimed towards a DirecTV satellite signal, the system will not work.

Our LNBs connected to the dish sends the signal from the satellite in space, which the receiver decodes so you get the picture for the channel you want to watch. A shaw receiver doesn't have the coding to decipher our signal.

To receive a Satellite signal, you need a LNB which is attached to your satellite dish--The LNB and dish is determined by which satellite TV service you have--either Dish Network or DirecTV. The satellite dish is pointed in a particular direction to pick up the correct satellite orbiting the sky. You will also need a satellite receiver, which is "wired" to the LNB and also is attached to your television.

strong rains and thunderstorm slightly affects signal blizzard covers the satellite dish with snow strong wind dislocates the position of the satellite dish strong heat, sometimes, can melt components of the satellite dish such as the surface of it

The satellite signal uses microwave radiation and water absorbs microwaves. So when it rains or there are thick clouds the signal from the satellite gets absorbed and if enough is lost by this process your Dish Network receiver will lose signal

There are no requirements to set up a satellite dish if you are just looking to receive a signal. There are signal transmitting requirements if you wish to project a signal that goes through licensing, content, and national standards.

The LNB takes the signal reflected off the dish, sends that signal through the coax cable to the receiver, where the receiver decodes the signal unlocking the channels you subscribe to.

Not possible. Due to the high frequency (4-12 Gigahertz) of the transmitted signal, it cannot pass through buildings and other objects. Therefore the dish needs a 'line of sight' to the satellite.

No; the wavelengths of the radio signals used for satellite TV reception are too short.

Each satellite TV dish can be a different shape depending on what provider you have. Dish Network satellites are more round -- the reason they are round is to get the best possible signal using the LNB (a device attached to the dish) and the specific curvature of the dish; since all TV, Cable and satellite providers use some form of satellite to get your programming each dish is a slightly different shape depending upon what satellite they are pointing to in the sky.

The dish is the antenna. The dish shape causes signal that hits a larger area (the surface of the dish) to be concentrated on the actual antenna (the lnb).

The best form of dish is a Parabolic Dish - This captures the digital signal and because of its concave form bounces the signal to an LNB ( stands for Low Noise Block) and it is the receiving end of a satellite dish. The LNB must be pointing directly to the satellite overhead in orbit to receive the strongest and clearest signal. As with a normal TV antenna, it may be required for you to adjust the LNB in order to receive the highest quality (strongest and clearest) satellite signals available

You can't get a signal to your TV without a receiver box. The receiver decodes the signal for the channel from the satellite to your TV.

No, it will definitely not. It has to be outside, and facing the sky. If it is covered up in the attick, it cannot get signal.

You can get satellite TV to work virtually anywhere as long as you have a clear line of sight for the signal. Each company (e.g. Dish satellite , DirecTV) has different satellite orbitals, so it will vary by company as to where your Dish is pointed.

The Sky satellite is used to beam television signal around the world and into your satellite dish. Sky themselves use the Astra 2A satellite, which is fairly newly launched.
