The purpose of an antenna on a radio or tv set is so that it can get signal so we can view tv or listen to the radio
Pick up the electromagnetic radiation (in the radio or TV bands) so that it can be brought into the set as electrical signals. This is analogous to the purpose of your eyes: pick up the electromagnetic radiation (visible light) so that the information can be brought into your brain as nerve impulses. However the antenna is usually just passive, whereas you eyes contain much of the active processing "circuits" that extract information that would be inside the radio or TV set.
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
No, you can't use your house gutters for a TV antenna for a television set that is placed in your house.
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
A plasma TV set is just like any other TV set on the market. It can accept video/audio signals from an VHF/UHF antenna if it has an aerial VHF/UHF antenna input. It can also accept DVB-C or DVDB-S or DVB-T through the same antenna input. You have to refer to the manual that came with your plasma TV set to see what types of signals it can receive through its antenna input.
Yes, the amplified antenna will sometimes make the TV set work where a unpowered will not.
Height, direction, antenna type and down lead are major factors in receiving a good TV signal to the TV set.
This might be a description of a radio antenna.
i think.... and i only think this, it may not be correct, an antenna transmits as well as receives, an aerial only receives there is no difference between antenna and aerial. According to British spelling it is called Aerial and according to American English antenna. So there is no difference just the English In the U.S. sometimes antenna is used for rigid structures used to transmit or receive radio signals, while aerial is used for a simple wire hung between insulators used to transmit or receive radio signals.
The plural of antenna is:antennae, if you're referring to the appendages of an insect;antennas, if you're referring to aerials for picking up radio/tv signals.
You don't need a new TV or antenna. You need a Digital Converter Box. Go to a Radio Shack, Circuit City or Best Buy. Connect your old antenna to the converter box, connect the converter box to your old TV...all will be well.
