I've recently gotten a 4g antenna. They're supposed to make the signal for the mobile much better when you normally would have a really bad signal. I have to say that it's really working out great! I haven't been to a place where I haven't had a signal with this antenna. I can really recommend that you look this thing up. I think that you're really going to like it. Imagine having a signal when everyone else don't. Wouldn't that be great? I'm really glad I bought this thing anyways.
