Great idea for an antenna, but I give it two strikes. It says that it comes with a connection kit, but the documentation assumes you already have a way to connect the (coaxial?) cable to your phone. There is no connection kit included. The only parts included are the sticker to attach it to your windshield, a small packet of glass cleaner and one page of instructions. According to the manufacturer's Web site, if you try to remove the antenna after installation, you destroy the antenna. For now, I'd say it's better to risk someone ripping off your external antenna then taking a chance that this permanently mounted antenna will be compatible with your next phone.
