Different people see the boundar between VHF and UHF differently. I tend to regard UHF as starting at 200 Mhz.
The UHF frequency band used for GPS transmissions for clear reception and sending. UHF or ultra high frequency is meant for radio frequencies between 300MHz and 3GHz. Normal frequencies for GPS transmissions are 1575.42 MHz and 1227.60 MHz. UHF frequency band covers these GPS frequencies.
BBC 2 is broadcast on a UHF frequency band, specifically in the range of 470-694 MHz for digital broadcasts.
UHF stands for Ultra High Frequency
UHF is an acronym for ultra-high frequency. Frequencies in the UHF band (300 to 3,000 MHz) are/were commonly used for television broadcasting and such two-way communication applications as cordless phones and walkie-talkie radios.
Doordarshan operates at various frequencies depending on the region. It typically broadcasts in the Very High Frequency (VHF) band, between 174 to 230 MHz and the Ultra High Frequency (UHF) band, between 470 to 806 MHz.
Radio waves have a lower frequency than microwaves in the electromagnetic spectrum. They have the lowest frequency and longest wavelengths of all the electromagnetic waves.
Early television broadcasts were transmitted on VHF (very high frequency) radio channels. They moved to UHF (ultra high frequency) and have remained on that band since. These bands are used for terrestrial broadcasts. Satellite broadcasts use even higher frequencies.
UHF and microwave
Ultra high frequency.
Ultra high frequency.
The frequency. Oddly enough, uhf actually stands for Ultra High Frequency and vfh stands for Very High Frequency. VHF for old TV covered the range 90Mhz to 150Mhz UHF for modern TV covers the range 400Mhz to 800Mhz
A YAGI UHF antenna is made to be very directional and receive all the UHF frequencies better than any others. In the US, some digital stations are still on the upper VHS band, channels 7 to 13. More info can be found at www.tvfool.com.
