Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. This is because you are allowed to use higher power output compared with that of GMRO/FMS or BRS radios which are limited in power output and operate under Part 95 instead of Part 90. More Info. Some vendors are showing images of the VHF RT1 radio transmitting on 136.025 MHz, others show the RT1 transmitting on 136.225 MHz. You cannot legally operate under GMRS rules unless you have a valid FCC License in your possession when using these frequencies. The UHF band has a frequency range of 300 MHz to 3 GHz, and is used for everything from TV broadcasting and GPS to Wi-Fi, cordless phones, and Bluetooth. These can include simplex channels, temporary repeaters or temporary trunked systems. If the applied-for frequencies were allocated solely to the former Power Radio Service (IW), the application must receive concurrence from UTC, The Telecommunications Association, the coordinator of the former Power Radio Service (IW). The UHF (Ultra High Frequency) band spans from 380-512MHz, exception being the 420-450 MHz band, which is an Amateur Radio band and generally excluded from in-door RF coverage enhancement. Now lets consider a hypothetical extreme case using a high-power BDA producing 20 Watts per channel, or 43dBm, and instead lets use a splitter with only a 140dBc PIM rating. Almost any Business/Industrial Pool frequency can be used. BRS requires users to get a license to operate on this particular band.
