Why car antennas are as long as TV antennas?
The length of an antenna is based on what frequency it is designed to send or receive. The higher the freq. the shorter the antenna. For instance, cell phone antennas are very short while AM radio antennas are long. CB antennas are 18 feet long but there are many exceptions where people have tried to design shorter versions that will still work well.

To remove an old television antenna from your roof, you will need aladder and a screw driver. You'll need to go up to the roof andunhook the antenna.
Yes, but to a very limited extent. . The most common indoor antennas generally may have rabbit ears, discs, and dials. The rabbit ears, contrary to popular belief, get the best directional signal when they are laid flat with both sides sticking straight out, perpindicular on a plane parallel with …the earth, and perpindicular to the line from the broadcasting tower. . The length matters, too, but it depends upon which station is being received. You can set the length in the middle, to the stations you like best, or adjust it for optimum reception for each channel. Loops should be arranged so that the plane that intersects the entire loop is perpindicular to the line from the broadcasting tower. Discs generally are plastic covered loops and should be arranged the same way. Dials make some adjustment in the electrical properties of the antenna. Try each dial position, do a full channel scan, and mark the positions that pull in maximum channels. Then narrow it down from there by watching the channels for a while. Now with that said, these rabbit-ear, loop, disc, dial antennas are not particularly directional because they do not make up for shadow signals that bounce off mountains and trees and buildings (whereas truly directional antennas, outdoor antennas and higher quality directional indoor antennas make compensations for these extra signals.). If the reception is still not satisfactory, then look for an antenna that is truly directional, omnidirectional, outdoor, or has a signal boost. Tuning for digital transmissions is complicated because the picture comes in perfect, not at all, or perfect with sporadic corruptions, which you don't see right away when tuning. For more about selecting an antenna and tuning it, read on... . Going by outdoor antennas (which have definite directionality), antennas specifically marketed as directional have a gun shape to them that you just point. Other indoor antennas are specifically marketed as omni- or multi-directional. With these, there is no problem with aiming. Although they may not be the optimal antennas when all stations are in one direction, they are probably just fine (as I believe they are usually of higher quality than the uni-directional ones.) The information below may also be helpful for aiming and fine-tuning indoor antennas for digital TV reception:. After finding the direction and distance of all the transmitting towers for digital television in the area (from the customized map at www.antennaweb.org), the next step would be to choose an antenna, hook it up, and aim it. . The antenna does not have to be "digital ready". Antennas are pretty much the same for analog and digital TV. (However, it is smart to know the characteristics of digital broadcasts in your area because of the difficulty in tuning to them.) You can start with whatever antenna you have, and if it does not work well enough, then research and buy a more appropriate one for your area. If you have no antenna at all, then try sticking the center wire tip of a cable TV cable into a potato or an orange--just to get an idea of the basic reception in your area. It will last a couple weeks until the vegetable dries out. . You need to be particularly choosy about your antenna if you want to receive channels 2-6, and to a lesser extent for channels 7-13. Channels 14-83 are the easiest to receive digitally, and most any antenna may do for those depending upon the distance and direction. If you are not satisfied with your reception on 2-13, but get 14-83 just fine, then you may want to just be patient rather than investing in an antenna: because of the large degree of difficulty with tuning these stations for digital transmissions, most stations are soon moving to the UHF band, channels 14-83. If you cannot wait, then focus on antennas designed specifically for both VHF and UHF (not only UHF in this case). In deciding whether you need a VHF antenna or not, you must realize that the stations have been renumbered and no longer represent the frequencies they broadcast on. For example, Digital channels 2-1, 2-2, 2-3, 2-4, 3-1, 5-1, 8-1, etc., are not necessarily broadcasted on VHF channels 2-8. To find out the broadcasted channels you must refer to a list like the one at www.antennaweb.org. (However, that website seems to only show the analog and dash-1 digital channels, not the dash-2 thru 5 channels, so another source must be sought). . If all the stations that you want are in the same direction from your house (within 20 degrees or so), then you can use a directional antenna and aim it right at the middle of the stations.. Outdoor antennas come in 2 basic types, directional and multidirectional. Multidirectional antennas do not have to be aimed. To aim a directional outdoor antenna, follow the directions from the manufacturer.. Indoor antennas are another story. They often come with no documentation, either in the box or on the manufacturer's website regarding tuning or aiming. They may only say turn the antenna until you get the best reception. This works fine for analog broadcasts because you can see the difference in quality when you turn the antenna. But digital broadcasts are different because the picture is either perfect or non-existent, or it corrupts at odd times and stops for a while (closed captioning may turn to gibberish, blocks of the picture turn colors or look like lower resolution, the screen freezes, and then a few seconds later it may restart).. To tune an indoor antenna for digital reception the best method may be to try different positions of the rabbit ears, disc, and dial, and write them down methodically, doing a new complete scan for channels each time, and then count and write down how many channels are found each time. This is a better method for digital because the number of channels found is a better indication of signal quality than the visible picture quality. Be sure not to do manual scans because those function only to add new channels not to count the number of channels receivable. This method would work best when all towers are in one direction.. If stations are broadcasting from different directions, then you should write down not only how many stations are detected, but which ones. Then your job is to come up with multiple settings combinations that get all the different stations you want at different times. After you have discovered them all, then do manual scans in each setting (if your TV has that function) to add all the stations. Then, keep a note close to your TV about which settings to use when actually watching each station. You may need only 2 settings to cover all your favorite stations (and in most areas only one setting will probably be satisfactory).. Since modern digital TVs have computers, one function really missing from them (exists in some models?) is a function to evaluate the tuning quality. Wouldn't it be great if your TV reported the signal quality it is receiving for each channel? I am not an engineer, but from what I know of the way digital TV works, it seems like such an easy function that I wonder if it is not already built in to TVs, but just not publicized. I am definitely looking for this function to appear soon. ( Full Answer )
antenna maybe defined astw structure associated with the transition between guided wave and free space (or) wise versa.
In Electomagnetics, Radio, Electronics, etc. : An antenna is a structure that couples energy between a circuit (radio, cell phone, etc.) and free space. The plural is antennas. In Biology, Zoology, etc. : An antenna is an organ used to sense the surroundings. The plural is antennae.
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 T…V set to see what types of signals it can receive through its antenna input. ( Full Answer )
I get a perfect picture on TV using an antenna. Can not get digital signal to come thru when using either a converter box or a new digital TV. I have following all the instructions carefully and can get no signal for digital. The antenna is new and hooked up correctly. Get perfect analog pictures. W…hy can't I get a digital picture? DTV signals are for the most part weaker than the old analog signals. Your new antenna needs to be a high gain VHF/UHF type with a built in or add on amplifier at the antenna. Don't forget to use new coax cable between the antenna amp and the TV set. Be sure the antenna is pointed directly at the transmitters, many have been moved. Sometime a rotor is a great help if the transmitters are in different direction's. If you using splitters, etc, they might need to be replaced with ones that will pass UHF (900 MHz) signals.

Sometimes a person has to make do with what they have around them.A homemade TV antenna would consist of a wire hanger and some tinfoil.
The short answer is maybe.. An antenna captures signals which are at a frequency the antenna was tuned for.. New Digital signals are being broadcast in the same channel spaces as were previously assigned to television stations but because many were broadcasting both old and new, their digital sign…als may have started transmission at the upper channels of the UHF band. Many older antennas were tuned out by channel 64 and the newer range runs up to 158 near 1000 Mhz.. The older televison broadcast was on what used to be Very High Frequency bands.. Channel 6 for example is just below the range of the FM radio band with the video signal around 83 megahertz and the audio at 87. This is why you can here what sounds like TV on some FM radios.. By Channel 14 you have moved to the Ultra High Frequency range. This is where many police, fire, and ems radios operate in metropolitan areas around 470 Mhz.. The lower the frequency the longer the antenna is needed.. Cellphones operate mostly around 2000 Mhz or 2 "Gigahertz". You see what length antenna they need!. I don't sell antennas so this isn't a pitch. The new disc antennas "may" provide you a better signal because they are designed to be compatible with current HD technology. In addition, the new disc antennas are low profile and have better wind and weather resistance.. Some stations have been careful to make sure the viewers in their area are able to continue using the same equipment with the addition of a converter box to get their channel by keeping their new signal close in the same channel bandwidth as the old analog signal. This will allow the older antennas to pickup the hd signal unimpeded.. The remaining issue of course is the converter box which decodes the digital signal into an analog television. This is a must have in order to get the new signal on an older TV.. I would keep my eye out around New Years to see if retailers are pairing Converters with better antennas at a bundled price.

It is a small transformer that allows you to properly connect a 300 ohm "balanced" antenna to 75 ohm "unbalanced" TV set. It works by allowing a "balanced" antenna to combine its outputs (it has 2) to the single input of the "unbalanced" TV (the center conductor of the coaxial cable). A common us…e would be to connect a pair of rabbit ears to the cable TV input of your TV. ( Full Answer )
\n. \n. \nThe short answer is , metal antenna elements are tuned by length and diameter to resonate at a electro magnetic frequencies of the tv channels.

\nIf you are mounting an antenna on top of your house or out on a pole, then you need to ground it from lightening strikes. IF you don't, the lighting will strike the tallest thing around your house and the current will flow through the wire and cause damage to anything and everything in your house…. \n. \nBut I don't know how to do this. It usually involves attaching a wire and to a stake that is driven deep into the ground. You need to ask an expert.\n. \n. \nBTW, lightening struck a power pole next to my house and it traveled into my house. The lightening damage required me to replace a heater/air condition controls, dish washer, TV, and garage door opener. But it didn't harm my computer equipment. ( Full Answer )
yes umm you have too hook the antenna to the hole ane wrap the copper wire around it-------------------------------------------------------- It would work OK for FM radio frequencies (88-108 Mhz) in metropolitan areas, but poorly for AM radio which is 535-1600 Khz
its collects data from space. It is a device that converts electrical energy into Radio waves or TV waves sending them out or receiving them.
There're 2 ways to solve this problem:. 1. Use car specific antenna adapters. Go to any local sound shop or even Best Buy and tell them your vehicles make/model. They should have one in stock or at least be able to order one for your specific vehicle.. 2. It will not cost much to change TV antenna…, no more than $20 to get double antennas.

The TV needs to be connected to something that provides the signal that you're going to watch. That can be a cable from your cable company, a satellite dish, an antenna, or just a DVD player if everything you want to watch is on DVDs.
An old antenna blowing in the wind can be troublesome causing flickering in the picture, etc.
The antenna can't tell if it is receiving analog or digital. They are the same. However, some antennae are 'banded' to receive a group of channels and reject others. A high band antenna in a weak signal area may not receive the low band digital channels with sufficient strength to 'lock'.
The TV needs to have two RF inputs. Most don't. Otherwise you need a A-B rf switch, Radioshack has them. Or you can connect the cable box to the TV using the VIDEO IN connectors leaving the single RF (antenna) input for the antenna.
An aerial. This is an old time term and not used in the USA much today.
There is more to a simple TV antenna than it appears, buy one and connect it with coaxial cable. Height is important so get it as high as possible.
The main differences have to do with their frequency of operation:AM radio and SW radio antennas operate at much lower frequenciesthan TV and FM radio antennas. An optimal low frequency antenna ismuch longer (and is usually operated in "quarter wave" mode toreduce its length) than an optimal high fr…equency antenna (which isusually operated in "half wave" or even "full wave" mode). Howeverthese differences are typically more significant at the transmitterantenna than at the receiver antenna. AM radio receivers often use a nonadjustable ferrite coil antennaor flattened coil antenna hidden inside the receiver to produce theeffect of a long nearly optimal antenna in a small space. TV and FM radio antennas are often an adjustable whip antenna orrabbit ears antenna mounted on top of the TV or radio, making iteasier for the user to optimize reception on different stations.

Depends on what type of truck you have. On current production Freightliners, Volvos, and I believe Internationals, the CB antennas also provide reception for the AM/FM radio and television.
no old technology televisions used to but modern advances but the more recent ones do not
With analog TV, usually the picture improved slightly, as our whole bodies were being used as an antenna. I don't know if that phenomena holds true with digital signal broadcasting or not.
Ok so the first thing you want to do is take the dish, and use the screws that came with it to masturbate and get someone to do it for you, don't forget to take some sperm and dribble it on your childrens heads
Yes, a tower can hold a antenna high off the ground allowing a better signal to the receiver or from the transmitter.
The tv antenna should point toward the broadcast station's transmitter tower. South has nothing to do with it.
No you don't, if you have a good reception with your analogue antenna you can connect it to your Digital TV and it will allow you to see digital channels including HDTV. There is a trend by manufacturers to add 'digital' in front of devices in order to sell them. There is nothing 'digital' about an …aerial, there are no embedded electronics. Having said that, there is a recommended type of aerial design, which suits the digital broadcast better. You need a 'wide band' aerial for best results. This is because the multiplexed, digital channels, in any given area, cover the whole spectrum of the UHF band, from channel 21 to 69. Your aerial needs to be sensitive across this wide band. Previously, with analogue, each region grouped the 4 or 5 channels together in one small part of the band (to stop interference from other regions). The antenna could be made cheaper and smaller if it was restricted to one small part of the band. UHF aerials have colour coded plugs in the end of the reflector support, to show the part o fthe band covered. Wide band aerials are black. If you are missing whole blocks of digital channels, it could be that your aerial isn't wide band. If you get all stations with no freezing or pixellating, job done, don't fix it. ( Full Answer )
The digital TV antennas were made when the analog satellites for TVs went to a Digital satellite. With a converter box and the digital antennas it still makes it possible to use TV that still use the old rabbit ears.
Comcast will provide you with a digital tv box that allows your television to receive the digital signal and therefore you won't need the digital tv antenna.
The best digital tv antenna usually depends on where one lives and whether one lives in a house or an apartment building. Some of the antennas usually offered are Antennas Direct DB2, Channel Master 4220HD, and Eagle Aspen DTV2BUHF
Outdoor antennas don't stand up well. I would replace an antenna after 5 to 7 years even if it looks ok. a new antenna with new lead in coax cable would improve the signal to the TV set..
Try a regular off air UHF/VHF antenna which cover channels 2 thru 69. while there are a few VHF stations (channels 2-13) still on the air most are UHF (channels 14-69) and are HDTV. This info applies to stations in the USA.
If the TV antenna was built for the correct frequency, it would work but my second thought is do you want the antenna to send a directional signal? I would think a "omni" signal (all direction pattern) would be a better choice. Most TV antennas are directional.
To start with, TV antennas only receive signals within a certain range. In addition, they are electrical conductors which act as lightening rods meaning an electrical arrestor must be used. Outside antennas can be dangerous to install because they require rooftop work.
You may find digital TV antennae at any retailers that sell TV sets.There are also many sites on line that sell antenna also, this is the best answer I can give on this question. I wish you luck.
Digital antennae for televisions are widely available at both retail locations and online sites. Wal-Mart, Target, Amazon, and eBay, for example, all stock this item.
Why do you need a voice controlled TV Antenna? TV antenna are fixed so you don't need voice control. Satellite TV Aerial may require change of position to face the satellite and you do have motorised automatic aerials which changes position when you change the TV channel.
There are two main types of HD TV antenna: indoor and outdoor. To use an indoor antenna, one simply connects it to the relevant port in the back of the tv, switches it on at the mains and then proceed to find the correct channel settings. An outdoor antenna is generally placed on the roof or high up… and may require masonry drilling and electrical connection, so is best left to the professionals. ( Full Answer )
One may attach an antenna cable to their TV in an extremely straightforward manner.

Television antenna amplifiers increase/boost a signal for transmission usually in the 70 Ohm or 300 Ohm range. The key advantage is that it removes the need for creation of a new broadcast location to extend a signal's range.
One can purchase an indoor TV antenna at various online stores such as Best Buy, and Overstock. Amazon and eBay also have indoor TV antennas for sale.
A TV antenna booster boosts the signal from the TV antenna to the broadcasters. It is useful if houses are far away from the broadcasters' towers such as in the countrysides, near the coasts, etc.
