2 Meters
(Redirected from 2 meters)
2 Meters is a popular amateur radio band. It ranges from 144 to 148 MHz in the United States, and from 144 to 146 MHz in most other parts of the world. The 2 Meter band is part of the VHF spectrum, and is primarily used for local communications, within a range of about 100 miles. Because it is local and reliable, and because in many parts of the world, the licensing requirements to transmit on the 2 Meter band it are easy to obtain, this band is one of the most popular non-HF ham bands.
