The so-called "2 meters" Amateur radio allocation is the band of 144 - 148 MHz
in the US.
Frequencies from 30 to 300 MHz are tagged 'VHF'.
'VF' typically means 'voice frequency' and is irrelevant to this discussion.
"HF" = 3 to 30 MHz.
"UHF" = 300 to 3000 MHz.
UHF grossed $6,157,157 in the domestic market.
Digital transmissions are on the TV channels 2 to 60, this is the VHF and the UHF band. Some stations changed frequencies and added new channels.
Not only on Motorola Portable radio, but in all radio communications: Frequency is number of cycles (full change circles) per second. When radio device operates on some frequency it requires band of adjacent frequencies to be able to transmit modulation (information) too. To avoid mixing, next transmitter must take some "distance" (higher or lower frequency) far enough from frequency of the first one. According to regulations basic frequencies are "named". Channel number is the name of its frequency given by communication regulations. For example, TV UHF channel 21 takes all frequencies from 512 to 518 MHz (megahertz), channel 22 from 518 to 524 MHz, and so on... CB Radio channels 21 and 22 occupy frequencies from CB band, not from TV band. Tables of channel frequencies within various bands can be easily found by search engines.

The 2 meter band is part of the VHF radio spectrum and is primarily used for conversation which theæ'hams' call 'rag chew'æand emergency broadcasting.
UHF CB radio is a type of personal radio in Australia. It stands for UHF Citizen's Band radio and operates similar to that of a two-way radio without any licensing fees.
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.
Yes, Bluetooth operates at radio frequencies between 2400 MHz and 2483.5 MHz in the 2.4 GHz UHF band using frequency hopping spread spectrum techniques.
TV broadcast signals are in the VHF & UHF radio bands, shorter than most of the radio bands but longer than the microwave band.
Microwave is entire of shf and uhf band
Motorola UHF radio is most famous for its ability to transmit radio in tow possible directions. This technology allows for communication as well as ease of listening.
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
Different people see the boundar between VHF and UHF differently. I tend to regard UHF as starting at 200 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.
In radio terms it means ultra high frequency.
