antenna, aerial, transmitting aerial(noun)
an electrical device that sends or receives radio or television signals
sensitivity similar to that of a receptor organ
"he had a special antenna for public relations"
one of a pair of mobile appendages on the head of e.g. insects and crustaceans; typically sensitive to touch and taste
(Electronics) A metallic device, variously shaped, designed for the purpose of either transmitting or receiving radio waves, as for radio or television broadcasting, or for transmitting communication signals. Some types are: whip antenna, antenna tower, horn antenna, dish antenna, directional antenna and rabbit ears. See transmitter, receiver.
Origin: [L. antenna sail-yard; NL., a feeler, horn of an insect.]
A feeler organ on the head of an insect, crab, or other animal.
For multiple feelers the Anglicised plural, antennas, is used only rarely in scholarly works in the life sciences. In other subjects and in less formal settings, antennas is found with increased frequency.
An apparatus to receive or transmit radio waves and convert respectively to or from an electrical signal.
For multiple aerials both plural forms are acceptable in scholarly works. The Latinate plural, antennae, is rarer in less formal settings.
Some make a distinction between an and an aerial, with the former used to indicate a rigid structure for radio reception or transmission, and the latter consisting of a wire strung in the air. For those who do not make a distinction, is more commonly used in the United States and aerial is more commonly used in the United Kingdom.
The faculty of intuitive astuteness.
For the faculty of intuitive astuteness, the Latinate plural is used most frequently but both forms are found.
Origin: From antenna, nautical term for yard and common term for pole, of unknown origin.
a movable, articulated organ of sensation, attached to the heads of insects and Crustacea. There are two in the former, and usually four in the latter. They are used as organs of touch, and in some species of Crustacea the cavity of the ear is situated near the basal joint. In insects, they are popularly called horns, and also feelers. The term in also applied to similar organs on the heads of other arthropods and of annelids

An antenna is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves. In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise. Typically an antenna consists of an arrangement of metallic conductors, electrically connected to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields, when created in the proper proportions, radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna.

When an image is taken there's a separate unit called the satellite node, and the images are sent via radio frequency to the satellite node and then the satellite node uses the Iridium Satellite Network to send that image to where you need it.
SEWIP is the Navy’s continued push to keep electronic warfare excellence ahead of the threat. It is an incremental set of upgrades to the SLQ-32 which was designed in the late 70s and deployed in the 80s. It gives the Navy the ability to upgrade and outpace the threat. It provides the ability to quickly upgrade processing as new threats come online and become more complex without overhauling the antenna.
