I have heard mixed reviews on these, mostly that they do not work well if at all.

have you tried the sticker antennas that paste behing the battery?

I am sorry if this is not posted in the right spot. I use my cell for my job and it is great when I am anywhere outside my home.When home I have to be in one spot in the house and even this is spotty. If I walk down my driveway maybe40 feet I can get a signal. I have people calling me during business hours and if I am home I can't take the call. Is there a low cost antenna I can buy or build that will work? I thought about the stick on glass type used in cars, but my windows are double pane so not sure if it would work. Thank You for any help, Tim
