What is a 800mhz radio? What is different from other radio such as VHF and UHF?

Answer 1

800 MHz radios operate somewhere in the frequency range of 806 to 902 megahertz. VHF radios operate in the VHF band. UHF radios operate in the UHF band. While the VHF band is traditionally defined as 30-300 MHz and the UHF band is traditionally defined as 300-3000 MHz, which would obviously include the 800 MHz band, UHF radios, as the term is usually used, typically operate somewhere in the range of 406-512 MHz, making UHF a separate band from 800 MHz.

Note also that 800 MHz is home to cellular and SMR (specialized mobile radio) bands, as well as the 800 MHz business and public safety landmobile bands. Interference to public safety 800 MHz radios from cellular and SMR towers has caused the FCC to undertake reorganization of the 800 MHz band plan and open a 700 MHz public safety band. See link below for details.

So, to summarize, 800 MHz radios, VHF radios, and UHF radios all operate over different (and incompatible) frequency ranges. There are also typically also other relatively minor differences, such as their channel spacings, their repeater offsets, and their bandwidths.

Answer 2

800 mhz refers to the frequency that the radio transmitts on, just like a radio station. VHF is very high frequency, UHF is ultra high frequency.

Answer 3

800mhz is a frequency. Mostly used by City, State and some Federal agencies for their radio communications. This can be heard on police scanners. Cell phones went to 900mhz.
