description={Radio frequency is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 \gls{GHz}. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves.%

Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as \gls{UHF}%

Lower frequency signals fall into the \gls{VHF} or lower bands.%

description={a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes -- one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument. Rotation about the horizontal axis varies the altitude angle (angle of elevation) of the pointing direction.
These mounts are used, for example, with telescopes, cameras, and radio antennas%
