If you have a compatible uniden scanner, this does work well and connects to satellites fast. It allows you to drive to new areas and it auto acquires local signals. I have not used this for this purpose though, i thought it might be a quicker way to get local channels, but it doesn't work that way. It's made to be used in your car. So if you do drive a lot for your job, then this might be something you would probably want to try. For at home though, it's not needed. Oh and it does use the sirf star III chip set, so it acquires satellites fast.
