Base station radios are simply mobile radios which are stationary. They usually sit on a desktop and have a power supply attached within a frame, along with an external antenna. While the radio is not portable, you gain considerable power and range with a base station radio. Base Station radios generally have transmit power levels of 25 to 50 watts. 

To get the longest range, use an antenna installed outside and mounted as high as possible. But, if range is not an issue, the simplest antenna solution is a mag mount mobile antenna placed on a metal surface such as a file cabinet.
