A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
This model was the first dual band radio (VHF/UHF) to be successfully distributed by a Chinese brand. [citation needed] It is inexpensive and relatively simple to use (though tedious to program without computer software). Because of this it is used by radio amateurs, outdoorsmen and professional users worldwide, outputting about a 4 watt FM signal.
A quattro LNB has a single feedhorn and four outputs, which each supply just one of the K u sub-bands (low band/horizontal polarization, high band/vertical polarization, low/vertical and high/horizontal) to a multiswitch or an array of multiswitches, which then delivers to each connected tuner whichever sub-band is required by that tuner.

[10] [12] GPRS devices can typically use (one or more) of the frequencies within one of the frequency bands the radio supports (850, 900, 1800, 1900 MHz). Depending on the device, location and intended use, regulations may be imposed either restricting or explicitly specifying authorised frequency bands. [12] [13] [14]
