OSDMA VHF Details

 
Select District Name :

The VHF (very high frequency) range of the radio spectrum is the band extending from 30 MHz to 300 MHz. The wavelengths corresponding to these limit frequencies are 10 meters and 1 meter.

In the VHF band, electromagnetic fields are affected by the earth's ionosphere and troposphere. Ionospheric propagation occurs regularly in the lower part of the VHF spectrum, mostly at frequencies below 70 MHz. In this mode, the communication range can sometimes extend over the entire surface of the earth.  

The VHF band is popular for mobile two-way radio communication. A great deal of satellite communication and broadcasting is done at VHF.  Channels and sub bands within the VHF portion of the radio spectrum are allocated by the International Telecommunication Union (ITU).
