• Boosts reception virtually anywhere as long as there is at least ½ bar of antenna power
• Static is reduced
• Easy to install
• Each booster is individually packaged
• No tools required for installation

Features: - Works on any digital or analog cell phone, pager, wireless telephone, PDA, etc, as long as you have access to the battery compartment. In some cases, it may be applied to the back cover of a device, behind the battery (like in PDAs). - Boosts reception virtually anywhere as long as there is at least ½ bar of antenna power. - Static is reduced - Easy to install - Each booster is individually packaged - No tools required for installation How does it fit? The Antenna Booster is easy to install. It comes with its own backing self-adhesive sticker. Just slip it underneath the phone's battery, and enjoy clear, enhanced, static-free reception. How does the Antenna work? The Internal Antenna Booster is a passive device designed to capture stray radiation in the body of the phone and re-radiate the signal to improve the phone's performance. The Antenna will work most efficiently when installed properly to reduce static (analog) and momentary cut-outs (digital) and increase clarity. Will the Internal Antenna help me get reception in dead zones? No. Despite what other resellers may claim. The Antenna Booster enhances a signal that's already in the area. It will not bring in a signal where there is none and cannot improve battery life. What models does it fit? It will fit all models except Nextel 500 & 800 series and any models with a screw-back battery compartment.

Have bought one of these years ago, but this one did not do much of anything for my reception problems and dropped calls with my Samsung slider phone. Worst reception phone I have ever had, and was hoping this would help. Did raise the bars in some places, but not enough to solve phones internal antenna problem. ..... at least it wasn't too expensive. If I remember, I think it did help phone of past that was a Motorola flip phone.... if that helps ya.

I ordered it in hopes that it would do something, but im convinced that it serves absolutely no purpose. However in an attempt to sound fair, it might have raised the bar by one level, but i just don't think so.

Can't tell how much this antenna really helps, but it doesn't hurt reception in any way so for the price you can't go wrong. They are still sold in the stores for 10 times as much.

I thought I'd try this since I was desperate and it was cheap, but as someone who studied engineering, I really should've known better. Whoever created this has got to be relying on the desperation/gullibility of people. How in the world is a thin sticker, no matter what's painted on it, supposed to catch some ambiguous "rays" and use that to boost signal? Just think about it.

This is VERY inexpensive: it costs a penny, and while the shipping is far too high for an item that could be slipped into a first class envelope, it's still relatively inexpensive.

That's why I tried it. I figured that I wouldn't be out too much money.

Does it work? I'm not sure. I haven't been able to conduct controlled experiments - only a scientist could - but I can say that it *seems* to give the phone the *tiniest* of boosts.

So, it depends on how much you're willing to sacrifice for a tiny, and almost imperceptible boost in signal strength (if there even is one; the boost I noticed could easily be a product of my hopeful imagination).

As for me, I wouldn't buy one again.
