The operating range of any radio system depends on terrain, power, antenna efficiency and many other factors. Actual performance will vary depending on local conditions, but it is possible to generally predict range under average conditions in an urban area. The table below specifies the maximum and typical ranges of radios by power output.
| Power Output | Typical Range | Maximum Range |
| 0.5 watt handheld | 1 mile | 2 miles |
| 1 watt handheld | 1.4 miles | 3 miles |
| 2 watt handheld | 1.7 miles | 4 miles |
| 4 watt handheld | 2 miles | 5 miles |
| 5 watt handheld | 2.5 miles | 6 miles |
| 25 watt mobile | 5.7 miles | 14 miles |
| 40 watt mobile | 6.5 miles | 17 miles |
In order to communicate in a wider area than can be reached from radio-to-radio, users must subscribe to a service that uses radio towers. These services such as Nextel and community repeaters, provide use of towers that allow two-way radio communications throughout several states.
Daily battery life depends on the capacity of the battery. Battery life is usually rated on an 10% transmit, 10% receive, and 80% standby. Most standard batteries will provide an 8-hour day before needing to be recharged. High capacity batteries typically provide 12-15 hours of use. These times will vary based on amount of transmit time, scan settings, age of battery.
Batteries are warrantied for 1 year and will usually last 2-3 years before needing to be replaced.
No, analog radio transmissions can be scanned. However, only someone within the operating range of your radio could hear any transmissions. If you need private conversation, consider a digital two-way radio such as the Nextel service.
The answer to this question will vary upon your needs and intended use. Compare the options using the table below.
| Handhelds | Mobiles | |
| Operating Range | Up to 6 miles without tower use | Up to 17 miles without tower use |
| Power Source | Battery | Uses vehicle power source |
| Repair Cost | More prone to physical damage (dropped, water, etc.), batteries will need to be replaced every 2-3 years. | Usually lower repair cost than handhelds due to fixed mounting position. |
Ni-Cad or Nickel Cadmium batteries are the most common battery used to power two-way radios. They may develop a memory if not cycled properly. NiMh and LiIo batteries offer longer daily battery life in a smaller package than Ni-Cads and will not develop a memory.
