Our New & Improved UNIVERSAL booster. The ORIGINAL and EFFECTIVE ultra-thin metal gold Cell Antenna Signal Booster works like a dish on a satellite to capture and emit a stronger signal. Mount the Cell Phone Antenna Booster internally under battery or externally to your cell phone. By placing the internal antenna behind the fixed antenna of the phone or attaching it to the back of your phone, you increase the surface area for sending and receiving messages.

Universal booster are better than ever! The antenna booster is now stronger, and comes in a shiny gold color. It also comes with instructions on how to install and test your new antenna booster.
 
This device collects the stray cellphone waves around the phone and directs it to the cellphone’s own antenna to help increase the phone's signal (this is why it's important that the booster must be in the same direction as the internal antenna.)

You must be careful not to nick or scratch the gold foil antenna. Do not remove antenna for repositioning or change to a new phone. This will most likely break down the integrity of the ultra-thin foil antenna wrecking the circuit
