The listing, Generation X Cell Antenna - Free Shipping! has ended.
From the front of the package:
Retail price $19.99
It's like having a four foot antenna on your phone.
Works with all cell phones, walkie talkies, pagers, and cordless phones.
Reduces static, improves signal strength and extends cell range while using your cell phone in elevators, tunnels, buildings, and remote areas.
Brand new. Never opened. Free shipping.
Note from seller - The instructions say to install it under the battery, however, I have found that it works best if you place it as near as possible to your device's internal antenna. I have an iPhone and I placed mine on the OUTSIDE pointing down, because my phone's internal antenna is at the bottom and I can't get to the battery. I went from no service (at work) to 3 to 4 bubbles (bars of service) after installing it. And it's peel and stick so you can adjust it's location if needed.
I ship to Listia verified addresses only. I will not ship to an address sent via message.
