Gain : How much more effective an antenna is as a radiator than a half wave dipole (dBd) or a theoretical point source (dBi). A more directional antenna is considered to have higher gain.

Ground : A direct connection from electrical equipment to the Earth - often achieved by driving a conducting spike into the ground, and connecting equipment to it.

GMT : Greenwich Mean Time - the time at Greenwich UK. Also known as Zulu and UTC.

GOTA : (1) Get On The Air - a station available for supervised public use at Field Day events,

GOTA : (2) Guides On The Air - a programme sponsored by YL organisations to introduce Girl Guides to amateur radio (see also: Jamboree on the Air)

G-TOR (Golay - TOR) : A digital FSK mode that offers faster transfer rate than PACTOR. Rarely used by ham radio operators.
