Handheld portable wireless two-way radios are the walkie talkie type of radios you see people carrying around. As ruled by the FCC (Federal Communications Commission), handheld radios may not have more than 5 watts of power.

Vehicle-mounted mobile two-way radios mount in a car or truck and they use the vehicle’s battery for power. They may have their own antenna, but better range is achieved by using an externally-mounted antenna.

Desktop base station radios use wall AC power and they too may have a built-in antenna, but this antenna may be disconnected and then connected to cable that leads to an external-mounted antenna. The higher the antenna is mounted, the better the range. The vehicle-mounted mobile radios are usually used as base stations by just adding an AC to DC power converter.

Mobile and Base station radios are usually more powerful than hand-held radios and may have as much as 100 watts of power.
