UHF connector - The UHF connector is a pre-World War II threaded RF connector design, from an era when UHF referred to frequencies over 30 MHz. UHF connectors are generally usable through what is now know as the VHF frequencies and can handle RF power levels over one kilowatt.

Captive Rover - A captive rover is an amateur radio mobile station equipped to operate on one or more VHF, UHF and Microwave bands during ARRL VHF or UHF contests who is forced to operate in locations that he does not want to operate and contacts only one other contestant. It's not clear if a captive rover is real, or a figment of the imagination of stations who often lose the contest.

Maritime broadcast communications net - In telecommunication, a maritime broadcast communications net is a communications net that is used for international distress calling, including international lifeboat, lifecraft, and survival-craft high frequency (HF); aeronautical emergency very high frequency (VHF); survival ultra high frequency (UHF); international calling and safety very high frequency (VHF); combined scene-of-search-and-rescue; and other similar and related purposes.

Very high frequency - Very high frequency (VHF) is the radio frequency range from 30 MHz (wavelength 10 m) to 300 MHz (wavelength 1 m). Frequencies immediately below VHF is HF, and the next higher frequencies are known as Ultra high frequency (UHF).

Keep an eye on your home or work on any TV with this OS110 Home Sentinel Motion Sensor Security Camera. The MUF for most of the earth is generally between 25-35 MHz. The first UHF TV broadcasts in Australia were operated by Special Broadcasting Service (SBS) on channel 28 in Sydney and Melbourne starting in 1980, and translator stations for the Australian Broadcasting Corporation (ABC). The frequencies of 300-3000 MHz are always at least an order of magnitude above the MUF (Maximum Usable Frequency). UHF and VHF are the most common frequency bands for television. Many Fox, UPN, WB, and Pax network affiliates broadcast in the UHF band. See also UHF (movie) Ultra high frequency This article is about the radio frequency. Recently, with the launch of BBC TWO in 1964, using a 625-line system (which had higher resolution, and therefore required greater bandwidth, than the existing 405-line system). The movie UHF, starring Weird Al Yankovic, parodies this phenomenon. In the United States, UHF stations (broadcast channels above 13) originally gained a reputation for being more locally owned, less polished, less professional, less popular, and for having a weaker signal than their VHF counterparts (channels 2-13). The UHF band is now used extensively as ABC, SBS, commercial and community (public access) television services have expanded particularly through regional areas. Today all British terrestrial television channels (analog and digital) are on UHF. However, the short wavelengths of UHF frequencies allow compact receiving antennas with narrow elements; many people consider them less ugly than VHF-receiving models United States On December 29, 1949 KC2XAK of Bridgeport, Connecticut became the first UHF TV broadcasts in Australia were operated by Special Broadcasting Service (SBS) on channel 28 in Sydney and Melbourne starting in 1980, and translator stations for the Australian Broadcasting Corporation (ABC). The frequencies of 300-3000 MHz are always at least an order of magnitude above the MUF (Maximum Usable Frequency). UHF and VHF are the most common frequency bands for television. Many Fox, UPN, WB, and Pax network affiliates broadcast in the main transmitters' coverage, which would not have been necessary wth a VHF system due to its different propagation characteristics.
