A radio telescope gathers and focuses radio waves, or electromagnetic waves outside the visual spectrum. A satellite telescope is sent outside the atmosphere to become a satellite of either the earth or sun, unless it is sent outside the solar system like the Voyager spacecraft. Many satellite telescopes carry several types of telescopes in one package to gather as much information as possible, like the Hubble.

∙ 14y agoYou can think of it that way. A satellite dish is a parabolic antenna designed to focus radio waves transmitted from a satellite, to enable us to receive the faint and distant signals.
A radio telescope does the same thing, except that we're listening for natural radio sources generated by other stars. The basic principles are the same.
With optical telescopes, you can use a telescope to look at a sailboat, or you can look at a planet. Are you a sightseer or an astronomer? The same tool is used in each case.

Can the Hubble Space Telescope detect radio waves?
I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.
What is the size of dish antenna?
It depends on if you are getting HD service with Dish Network. If so, the Dish dimensions are 20.5"h x 22.5"w. Most satellite TV dishes are about the same size, they vary slightly to pick up the correct signals in orbit depending on what Dish programming you have.
Can you just unhook your satellite dish and hook up your antenna with the same coaxial?
Satellite and terrestrial both use similar co-axial cables so it is probably fine to use a satellite cable for an antenna. If the cable needs to be extended, be sure to use a suitable 75 Ohm co-axial connector to make the joint. Twisting the conductors together and taping them will cause problems.
When you use a radio telescope what happens?
You are receiving that portion of the electromagnetic spectrum that radios use. It is a much lower frequency than visible light and can detect things that glow at much lower temperatures than stars ... such as gas clouds Many radio telescopes use the 'hydrogen line' at a wavelength of 21 cm. That is one of hydrogen's spectral lines, corresponding to a transition between two high energy levels in the hydrogen atom.
What is the dtv green dish?
The DTV Green Dish is a new antenna, partnered with a dish and forms a highly directional, high gain system. It uses the parabolic reflector to focus terrestrial signals in a similar way to satellite dishes. It is claimed to improve reception with distant transmitters and the makers suggest it will be an improvement in all situations with guaranteed reception of all major channels. Buyers should probably have that kind of guarantee in writing before committing to the antenna. After all, it is breathtakingly expensive at $300. The antenna is limited to receiving only channels that are broadcast on the terrestrial channels. Don't expect it to deliver the premium cable and satellite channels.
Which instrument uses a dish antenna?
radio telescope does.
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
Does satellite radio work in inclement weather?
People who use satellite dishes for television reception are more apt to lose reception during inclement weather than someone who has a satellite radio. The difference is the dish and antenna. The dish is pointed in just one direction, while the antenna is omnidirectional. Because of this, those with satellite radios can still enjoy reception during inclement weather.
What is a spherical dish antenna required for satellite tv reception?
The parabolic antenna is really not an antenna at all - but a collector/reflector, which catches and concentrates RF (radio frequency) into a tiny antenna mounted above the dish, pointed into the dish. Since satellites transmit at very high frequencies (microwave), the actual antenna can be shorter than one inch. To strenghen the signal and make aiming the antenna at the satellite easier, the parabolic reflector picks up a wider area of RF.
When was the radio telescope first made?
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
Does a radio telescope have a dish reflector?
Yes.
Where can you get a backyard satellite dish?
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.
What is a radio telescope made out of?
Radios are electronic devices which grab signals and turn them into sound. They are composed of electrical circuits and of the various electrical and electronic components that are needed to make those circuits which in turn make the radio itself work.
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).
What is a statelite dish?
Satellite Dish is a dish-shaped type of parabolic antenna designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television.
Satellite dish used as an antenna?
They do not make very good antennas though.
In a radio telescope radio waves strike a large curved?
Concave dish
