Single Channel Ground Air Radio Systems (sincgars) can operate in VHF (very high frequency) low band 30.0000 MHz to 89.9999 MHz or VHF high band which is 90.0000 MHz to 224.9999 MHz
VHF uses the 6 Meter Band (50-54 Mhz), the most popular VHF band - 2 Meter Band (144-148 Mhz) and the 1 1/4 Meter Band (222-225). UHF uses the most popular UHF band - 70cm Band (420-450 Mhz), the 902-928 Mhz area and the 1200-1300 Mhz area.
It is used for sending wireless signals over the Very High Frequency band of radio. This band is mainly used for television signals. It can also be used to modulate a television signal in a single cable.
history of vhf radio
In a VHF (Very High Frequency) diagram, two mixers are typically used for frequency conversion to improve performance and selectivity. The first mixer down-converts the incoming VHF signal to an intermediate frequency (IF), allowing for better filtering and amplification. The second mixer can be utilized for further processing or to shift the signal to a different frequency band. This dual-mixer setup enhances the overall system's sensitivity and dynamic range, enabling more effective signal processing in communication systems.
the high frequency, it is in VHF band.

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.
A VHF ocsillator is a very high frequency ocsillator (30-300MHz). It oscillates (swings back and forth) at a VHF frequency.
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.
Very high frequency
FM radio stations transmit on VHF band, short for "Very High Frequency", ranging from about 87 to 108 MHz.
It is used for sending wireless signals over the Very High Frequency band of radio. This band is mainly used for television signals. It can also be used to modulate a television signal in a single cable.
Very High Frequency.
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
Different people see the boundar between VHF and UHF differently. I tend to regard UHF as starting at 200 Mhz.
