a metallic wire, rod, or combination of rods connected to an electronic device, designed to send or receive radio or television signals.

Cable or rod used to send and receive radio signals (connected to transmitter and receiver or tuner).

An aerial (or antenna) is a device for radiating and receiving electromagnetic waves in the radio frequency (RF) range.

an electrical device that sends or receives radio or television signals

a receiving or radiating device used in radio communications

On a transmitter a metal rod, usually collapsible, which radiates the transmitted signal; or a trailing or rigid wire on a receiver which collects the signal.

A device that collects and amplifies electromagnetic waves. Also called "Antenna"

An essential part of any radio. Usually made of some sort of metal (for Sea Cadet operation, copper is preferred) and may be wire, tubing, rods or a combination of these. An aerial is the interface between the equipment and Free Space. Some transceivers (e.g. later models of mobile phones) have the aerial built in, but, whether they are visible or not, they are always there. Some types of aerial are known as Antennas and there is some argument as to which is which.

See Antenna.

An array of metal wire used primarily to help a radio or television tuner locate and tune into broadcast signals. A complex multi-element FM aerial or yagi is required in areas far from radio transmitters. It comprises reflectors and directors, as well as the standard dipole.

A tuned length of conducting material used to transmit or detect radio frequency signals. The length of an aerial is determined by the operating frequency of the equipment in use. It is important that aerials are not trimmed or twisted back on themselves as this alters the effective length.

Used on the frontal monocoque just ahead of the cockpit for two-way radio or telemetry purposes.
