une parabole, une antenne satellite
If you are considering putting in a satellite dish, then you may have a few questions about how fast the feed is. You can expect a three to nine second delay when watching over satellite.
It is used for, taking information from tv stations and taking it to your tv.
Well, the satellite dishes in my area are mostly grey, not white - but to the question - why painted and not mirrored?. The wavelengths that need reflecting by the parabolic mirror of the satellite dish are in the microwave range - a millimetre or so. So, the dish need only be smooth compared to that length, and a paint finish meets that standard, though of course, most of the reflection is done by the metal of the dish. The paint need not be radio-conductive or radio-reflective. Were the dish needed to operate in the optical range, then indeed, a mirror finish would be needed.
I've had great success and fun by turning a satellite dish into a super directional microphone. Any small mic will work, just position it at the focal point in place of the old microwave amp facing toward the dish. Add small headphone amplifier and listen up!

A satellite dish is just a reflector of radio waves, and made in the shape of a parabola. The actual aerial bit is placed at the focus of the parabola, so you are getting all the energy that fell on the area of the dish. It will receive the energy transmitted from a particular satellite - usually an entertainment one.
There's only one: -- In a receiving dish, the collected and focused electromagnetic energy changes to electrical energy in the feed, LNA, or LNB at the focus of the dish. -- In a transmitting dish, the electrical energy of the transmitter changes to electromagnetic energy, either at the focus of the dish if the transmitter is mounted there, or else at the end of a hollow waveguide that escorts it to the focus of the dish.
Satellite dish is used to receive the data colleted by the satellite and to give commands to it.
A sky dish is a satellite dish that is used by companies such as Dish Network or DirecTV to receive their satellite signals. They are usually mounted on your home and pointed in the direction of the company's satellite.
If you are referring to the original satellite dish known as the C band satellite, the satellite company that used these was DISH Network.
To find a satellite dish antenna for sale, going to the local television company would be the first stop. Typically they have a wide selection of satellite dish accessories and satellite dishes.
You can usually get an HD satellite dish from your satellite company. Direct TV or Dish Network are two large companies that are available in almost every area. They have HD satellite dishes. www.dishnetwork.com
A Satellite Dish is used to receive and transmit signals which contains different information to or from the satellite.
the satellite dish and dog's ear are alike in some ways
Well, a major disadvantage or problem, of using satellite television services, is that whenever inclement weather occurs, a television set that is connected to a receiver that receives its signal from a DirecTV Satellite Television OR Dish Network Satellite Television Satellite Dish, glitches up.
It depends on what kind of motorhome and when you want to watch Dish TV. If you will be mobile and wanting television, you will need a self adjusting satellite dish; there are also stationary satellite dishes available. As far as a satellite system, I prefer Dish TV because of the price, channel selection and technology. Dish Network also has a affordable portable satellite dish that does not attach to your motor-home called the Dish Tailgater.
An HD satellite dish allows a customer to receive HD programming in their home via the dish attached to the top of their house. In order for this to be done, correct installation is needed or the dish might not be aimed at the correct satellite.
