The UHF band that could normally associated with television channels, is a Spanish band in the electromagnetic spectrum, ranging from 300 MHz to 3 GHz. The UHF band can be affected by variables such as humidity, solar wind, or the time of day that will attempt to connect the device. Although as positive could define the UHF frequency band is high, hence its advantages over short distances.Ultra High Frequency (UHF) Cycles per second: 300 MHz to 3 GHz Wavelength: 100 mm 1 m

The UHF connector, also called coaxial connector Amphenol is a RF connection design, created at a time when "UHF" referred to the frequencies above 30 MHz. Originally designed to be used as a video connector radar applications, the connector was later used for RF applications. This connector was developed on the basis of a shielded banana plug.

The called VHF is a Very High Frequency band (hence VHF) ranging from 30 Mhz. to 300Mhz.

The VHF is used for sending audio and video signals between a transmitter and a receiver or between a sender and multiple receivers (broadcast).
