    RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.
    These frequencies make up part of the electromagnetic radiation spectrum:
    Ultra-low frequency (ULF) -- 0-3 Hz
    Extremely low frequency (ELF) -- 3 Hz - 3 kHz
    Very low frequency (VLF) -- 3kHz - 30 kHz
    Low frequency (LF) -- 30 kHz - 300 kHz
    Medium frequency (MF) -- 300 kHz - 3 MHz
    High frequency (HF) -- 3MHz - 30 MHz (Davison build machine frequency range) 
    Very high frequency (VHF) -- 30 MHz - 300 MHz
    Ultra-high frequency (UHF)-- 300MHz - 3 GHz
    Super high frequency (SHF) -- 3GHz - 30 GHz
    Extremely high frequency (EHF) -- 30GHz - 300 GHz
    Radio frequency is also abbreviated as rf or r.f..
