It's like having a four foot antenna on your phone(((Cell Antenna )))Works on any mobile phone,cordless telephone or pager. reduces static, improves signal strength and extends call range while while using your cell phone / mobile phone in elevators,tunnels, buildings and remote areas.

INFO

The Cell antenna is a passive device designed to capture stray radiation in the body of the phone and to re-radiate the signal to improve the phones performance. The antenna will work most efficiently when installed properly. when using the phone try to avoid placing your fingers on the back of the antenna or on the part of the phone where the antenna will be placed.

Installation Instruction (see "best way to test booster" below if testing results are desired)

1. Remove the battery from the phone.
2. Wipe the battery compartment with a clean, dry cloth to remove any oils from fingerprints or dirt.
3. Remove the yellow from the internal antenna, being very careful not to touch the sticky area with your fingers. this could leave oils and residues from your fingers on this area possibly any of the internal components or circuits boards.
4. Press the internal antenna onto the body of the phone in the same direction as the existing antenna (if possible)

The best way to test the booster is as follows

1. Go to a known low reception area.
2. Check and make a note of the reception level.
3. Take out the battery
4. Install the booster according to directions - avoid touching the sticky part of the booster - stick it on the phone - not the battery - as close to and in the same direction(if possible) as the built-in antenna . In especially low reception areas - AND if your phone can hold more than one booster - go ahead and install a 2nd.
5. replace the battery
6. Turn on the phone.
7. Check reception.

You should notice at lease ONE bar more than before. Keep in mind that in a near Zero signal strength area (less than a continuous single antenna strength bar ) Results will be minimal. In areas where cell signals are non-existent, the booster will have no effect(but neither would a 10 foot antenna)
