A MURS Radio uses 150 MHz frequency which is a Citizens Band radio spectrum that is called the MURS service. MURS stands for Multi-Use Radio Service. This is a newly created service for use in the United States. It is a low power, short range service in the VHF (Very High Frequency) 150 MHz Citizens Band radio spectrum.
The FCC does not require users of products for these bands to be licensed, but it does impose strict regulations on the types of products and services that may be supplied to consumers.
Previously the FCC came out with the Family Radio Service (FRS) in the 462 and 467 MHz spectrum in which you can find handheld units, but no intercom systems based on this service. MURS radios are similar to FRS radios but they have a power increase of four times that of FRS radio. And unlike FRS, you can add a larger or external antenna to improve range. If you want to put an antenna on top of your house, you can do it with MURS. Some antenna manufacturers claim an external antenna can increase the effective radiated power of a transmitter by a factor of 4.
These MURS Radios can transmit up to four miles, and perhaps more with an external antenna. These units are not secure, but there are fewer systems in use and few devices outside of a scanner to intercept this frequency. The IntercomsOnline.com MURS Multi-Mile Intercom uses the MURS frequency.
Below is a picture of a MURS Radio base station that you can use to communicate with MURS handheld two-way radios. IntercomsOnline.com are MURS Radio dealers for this and other products.
