those things do nothing!!!!!!!!!!!!!!!!!! They made millions on them things and they are worthless.
something a friend of mine did, and I don't know if you can?/ Is buy one of them external att. they mount on the window. One half on the outside and the other one on the inside. there is no connection to the phone itself.
My friend says he went from 1 bar to 3 bars and he can use it in his office at lease.
no it was something like $25 I will have to get in touch with him, he is on vacation right now.
I will look alo as i was thinking about one at one time.
Perfect!!! Thanks guys! Looks like the one RAP posted is what I'm looking for, comes with 115v transformer. MJ, looks like yours are for cars only, I could be wrong though.
