Understanding the Range of a Two-Way Radio
Two-way radios are devices used to communicate with each other. Some are equipped with microphones and transmit sound using a push-to-talk button. They are also equipped with VOX technology, which stands for voice-operated exchange. When switched on, the VOX microphone listens to the user's voice and turns on the radio when it detects a conversation. Likewise, it will automatically shut down when there is no sound. To understand how different frequencies affect the range of a 2-way radio, you need to understand the difference between UHF and VHF frequencies. The lower the frequency, the longer the wavelength. Both frequencies produce similar levels of energy and are effective for the same purpose. When considering the distance of a 2-way radio, it's best to consider how much distance it ca...
