Works well indoors also

This antenna boosted the signal I have inside my apartment by 10dB according to the MA730 software on my PC that displays signal strength while my phone is connected to it via Bluetooth. I have it attached to the side of a baseboard heater and it virtually eliminates the frequent and repeated dropped calls I used to experience indoors. This product has worked when other solutions like special (screw-in) antennas or booster stickers on the phone itself did not. Setup is a breeze as is connecting and disconnecting the phone from the antenna. Just plug it in or pull it out and go.
