A walkie talkie is a type of radio that uses radio waves to communicate. They can communicate over several miles and over various terrains. They are designed to allow up to four people to speak at the same time. A typical walkie-talkie works with a microphone and a coil of wire. The most basic walkie-talkies have a microphone and speaker attached together. More advanced models have separate components. The radio's battery life varies, but batteries should be replaced every twelve to eighteen months or so.
The range of a walkie-talkie is limited. You will want to choose a frequency that is compatible with your surroundings. If you're using the radio for business, the frequency of your conversation will be Ultra High Frequency (UHF) or Very High-Frequency (VHF). You'll find that business-oriented devices are more durable and offer a longer range. However, they're also generally more expensive than consumer models.
Before buying a walkie-talkie, make sure to check out its range and capabilities. There are different types of walkie-talkies available for different purposes. Commercial walkie-talkies are often used in recreational activities such as camping and hiking, but amateur radio operators may also modify them to operate on amateur frequencies. These radios are more durable than their amateur counterparts, but they can only communicate over a narrow range.
