Gain: The increase in signal strength that is produced by an amplifier.
Generator: A device that changes mechanical energy into electrical
energy.
Ground: A very large semiconductive surface (the Earth) or a
smaller highly conductive surface.
Ground-Plane Antenna: A type of antenna that uses a ground plane as a simulated ground to produce low-angle radiation.
Ground radials: Wires on or in the earth to improve its conductivity
near the antenna.
Ground screen: A wire mesh ground plane.
Ground wave: A radio wave that travels along the Earths surface
rather than through the upper atmosphere.
Half-wave dipole antenna: A center-fed antenna whose electrical
length is half the wavelength of the transmitter or received signal. An antenna consisting of two rods (1/4 wavelength each) in a straight line, that radiates electromagnetic energy.
Half-wave vertical dipole antenna: A half-wave dipole constructed
vertical to the Earths surface.
Helical Antenna: An antenna with a spiral conductor wound around a cross section
Hertz: One cycle per second.
Hertz antenna: A half-wave antenna installed some distance above ground and positioned either vertically or horizontally.
High frequency: frequencies between 3 and 30 MHz.
Hop: A single reflection of the wave back to Earth at a point beyond the horizon.
Horizontal dipole: A dipole constructed parallel to the Earths surface.
Horizontal pattern: The horizontal cross-section of an antennas three-dimensional radiation pattern.
Horizontal polarization: Transmission of radio waves in such a way that the electric lines of force are horizontal (parallel to the Earths surface). Waves that are radiated with their E field component parallel to the Earths surface.
