in television, channels 14-83; generally, the signal of such a channel has a more limited range or coverage area than a very high frequency (VHF) channel. Assigned by the Federal Communications Commission (FCC). See very high frequency (VHF).
The UHF range of the radio spectrum used in legacy data collection computers is typically in the band extending from 400MHz to 450MHz. These radios are crystal based. These crystals must be grown and on occasion re-aligned because they have a tendency to drift.Its radio output power of 1w to 2w yields an effective range of one to two miles. Because of this, a site license is required from the FCC in order to use UHF radios in a data collection application.The data rate is about 19.2Kbps or less.
(UHF) To Very High Frequency (VHF) Converter- An electronic device for receiving UHF signals and translating them to VHF signals for transmission from the antenna to the processing equipment in the headend.
Limited-range wave bands for television channels (14 to 82) that transmit from 470 to 890 megahertz (MHz), with lower power and over a smaller area than low-band (channels 2 to 6) or high-band (7 to 13) very high frequency (VHF) stations.
Ultra high frequency (UHF) designates a range (band) of electromagnetic waves whose frequency is between 300 MHz and 3 GHz. Waves whose frequency is above the UHF band fall into the SHF (Super high frequency) and EHF (Extremely high frequency) bands; all of which fall under the Microwave frequency range. Lower frequency signals fall into the VHF or lower bands.
Ultra High Frequency is a Long Island, NY based rock band formed in the mid 1990s in Long Island, NY by Frank Fussa (vocals, guitar), Jon Tehel (guitar / vocals), Chris Johanidesz (bass / vocals) and Dennis Joseph (drums / vocals). It wasn't until 2004 with Dennis Joseph's return that the band's heat got turned on with their first official release "Sun Never Sets in Dramaville".
