I am planning to order my scanner soon. I am going to order from Scanmaster. I am going to get the GPS with it. Do you recommend getting software with it or one of the free ones online? I plan to program my area as well as areas that are on my route from Memphis to Arkansas, Memphis to Chicago and Memphis to south Carolina for when we travel to visit family. I am going to go with a roof antenna since there are already hole in the roof from the dapartment that had it. Recommendations of a cable and antenna to go with it? My local area runs on the 800-900Mhz range. Thanks!
