It is not the satellite dish that displays that it cannot receive a signal; the dish simply receives the signal. The converter box that is located near your television converts the signal (usually encrypted to prevent pirating) and displays such messages when it does not get enough signal strength from the dish to display the given station(s). If you see that message for an extended period of time, and the weather is generally good (i.e., no heavy clouds or storms), then you should call your dish company for help.
Before doing so, take a look at the check list below which may help to fix the problem or to diagnose it.
Sometimes, just turning the converter box off, waiting a minute or two, then turning it on may improve or restore the signal.
If your satellite system used to work but you started getting that message
more and more often and on multiple channels, then the most common causes are:
-- The hardware that mounts the dish to the roof loosened up over time,
and a few minutes of strong wind pointed the dish off in a new direction.
Maybe not even enough to see the difference, but enough so that it's
no longer pointed close enough to the satellite to receive a good signal.
It doesn't take a large move.
-- A branch of a nearby tree grew into the line of sight between your dish
and the satellite it's trying to hear.
-- One of the cable connectors at the dish was not adequately taped or
gooped when it was installed, and after some months out in the rain and
snow, the connection became rusty or corroded, and a big part of the signal
is being lost right there at the connection.
-- Snow, ice, mud, water, or leaves have collected either in the dish, or else on the small face of the receiver that sits out at the end of the arm and points backwards into the dish. (I have even seen one case where birds pecked holes in that 'feed aperture', and the rain blew inside, and another one where a small hole developed in it somehow, whereupon bees moved in to raise their baby beelets in there.)

What are some hardware used in video distribution?
Hardware used in video distribution varies heavily on the medium through which the video is distributed. Satellite video distribution requires the use of satellite platforms, as well as receiving dishes capable of processing the satellite signal.
Why are satellite dishes concave?
Because they act as a lens which focuses the signal into the LNB. If they weren't concave, they'd just refect the signal back into the direction from which they came.
What is the speed of a satellite signal?
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
If you have satellite internet can you get satellite tv?
If you can get a signal for your satellite Internet service, then without a doubt, you can also get a signal for satellite TV service AND the other way around also. The one thing you must know is that a no matter what anyone tells you, having both services will require two separate satellite dishes. The same provider that supplies you with Internet service can't provide TV, and vice versa. For satellite Internet, you'll need to use HughesNet, WildBlue, Starband, or Skyway USA, and for satellite TV, you'll need to use DIRECTV or Dish Network. That's why you'll need two separate dishes.
What is a bowl-shaped device for receiving television signals broadcast via satellite called?
The satelite is has a shape bowl because it is the one who cathes the signal,without it there would be nothing to catch the signal.
What kind of dishes do radio telescopes use?
Technically parabolic dishes like satellite dishes can be use as radio telescope but as the gain of signal is very weak on radio astronomy relative to satellite signal then you need to have bigger surface area or bigger dish. The minimum suggested size for use as radio telescope is 3 meter like RTP30 radio telescope from POAM Electronics company. ( for more information look at poam electronics website).
Why do local broadcast television stations have so many large satellite dishes?
Broadcast television stations are heavily reliant on communication with other television production organizations and content delivery companies. Although land based communications are becoming ever faster, the television industry has been built on satellite communication systems due to the very mobile nature of news and event gathering production units. Live news feeds can be obtained from almost anywhere in the world with a satellite transmission. The signal can be transported around the world an back to base stations with ease. TV stations use several satellites for incoming and outgoing signals, hence the array of dishes, all of which can be active at any time. Unlike domestic satellite dishes, commercial dishes need to be capable of receiving low power transmissions from satellites that are not always in ideal locations. The large size of the dishes allows higher signal levels to be captured, from satellites that many be low in the sky and also overcome the problem of weather related dropout occasionally experienced by residential dishes.
What is the purpose of the Earth station antenna?
The main purpose of the Earth station antenna is that it receives and RF signal, which it turns into an electromagnetic wave and sends to a satellite. It then transfers the energy from the satellite to different signals and sends it to receiving equipment.
Why No signal from satellite?
There are many reasons why you may have no signal from your satellite. Your service could have been disconnected for example.
Why is a satellite dish round?
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.
Where does the satellite lie?
A satellite again is a mirror; it is simply bouncing the audio and video signal, usually in C or KU band. The small dish companies receive this feed by way of dish farms, with many dishes pointed at different satellites. These dish farms then process the main signal and compress it, usually to mpeg format.
Is satellite or cable television a better option?
When it comes to satellite or cable, these days determining which is better is dependent largely on two main factors: Channel availability and location Some locations are not suitable for receiving a strong satellite signal which can result in channel/image loss. Some channels which are available on satellite are not available on cable.
