Do cell phone antenna boosters really work?

No, they do not... What they are supposedly doing is one of two things: (1) They are "connecting" (making contact) with the antenna in the cellular phone and expanding it (such as one can see with magnetic CB antennae on cars. Those magnetic bases often have a bunch of wire wrapped up inside them that effectively makes the antenna longer than the whip that is actually sticking out the top. I have never seen any test results that have shown it makes the reception any better but I understand the theory: the closer one gets to having an antenna that is the full length of the wavelength of the signal one is trying to receive, the better the reception is supposed to be.

The problem with the stickers is that they make more "contact" with the battery than they do with the antenna in most cases because the antenna raises and lowers inside the phone on the other side of the plastic "wall" that serves as the back of the phone facing the inside face of the battery. (2) They try to "amplify" the signal by passing it through its internal coils, essentially trying to build up electromagnetic field strength. This is kind of like if you take a bunch of extension cords (such as the 100-foot orange outdoor cords) hooked together and plug it into a wall socket, you will notice nothing as long as they are lying pretty much in a straight line.

However, if you put them in a coil, you will find that there is a massive electromagnetic field coming from them. Put them near computers and you can cause all sorts of problems. (I saw someone doing this one time with about 200 feet of big super-industrial strength electrical cords--the big, thick yellow ones that are about 1.25" in diameter and designed to carry LOTS of amps, much more than a house would have out of a single outlet--and it started frying the computers within about ten feet of the coil.

The electricians working in this computer lab were not the brightest of folks apparently. I got called into the situation to find out what happened to the computers after the fact. ) The problem with this theory is that the amount of power being received by the sticker is so infinitesimal that if there were any increase it would hardly be measurable, especially when talking about something that has so little mass and such short distance.

Beyond that, once again, the sticker is NOT in contact with the antenna, so it is not going to do anything useful since it would need to have a way to get the improved signal to the internal circuitry of the phone for interpretation and reconstitution into audible sounds. Now, the problem with both potential theories is that the material used to make the "booster" is so flimsy and pathetic in quality that even if either theoretical operation did hold water, the interference from the lack of quality would more than nullify any gain produced. Therefore, the conclusion is that these are nothing more than another "As Seen on TV" scam to part the unwary consumer from his hard-earned money..

They're a scam The idea is that they resonate at the frequency of cell phone signals, amplifying the signal and damping out noise. They don't. They might conceivably work if they were located precisely between your antenna and the cell tower and were designed properly, but that same design would cause interference if you turned your cell phone 90 degrees.

More likely, they're not really "designed" at all except to look electronicky and don't do anything at all. Tests confirm that they don't do any good. Which isn't surprising: the clever engineers at Motorola and Nokia would have included them in the design if they did do any good.

No. They don't work. The silly "internal antenna" and "booster antenna" devices, basically little strips of plastic that stick onto your phone, do NOT work, and there is no basis in RF theory for their operation.

Here is how they are supposed to work: 1) A campaign of cheap late-night commercials advertises them to the public. 2) People who don't know any better buy them. 3) Said people stick them to their phones.4) Strips of plastic do absolutely nothing.5) Consumers, not wanting to admit being duped, keep them and become convinced they work.

I used to absolutely scream at my television when those spots came on. They were so insipid and so patently fraudulent. Remember the blonde lady in the elevator?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
