I bought the antenna so I would have better reception in my basement. I had to run it out a window and the magnet holds it to the siding on the house (I placed plastic around it to prevent rusting). I have had 3-4 bars of signal, consistently and the calls seem clear. My Motorola Razr was useless and never had signal in my basement before I used the antenna. Only complaint is that the cord is a little short and it only worked after I put it outside (it didn't work by just placing it by the window on the inside).
