Cantenna vs. Antenna — What's the Difference?

A cantenna (a portmanteau blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. Cantennas are typically used to increase the range (or discovery) of Wi-Fi networks.

(Zoology) One of the paired, flexible, segmented sensory appendages on the head of an insect, myriapod, or crustacean functioning primarily as an organ of touch.

A directional waveguide antenna for long-range Wi-Fi, made from an open-ended metal can.

A structure in a photosynthetic organism containing pigment molecules that absorb light energy and transfer it to a reaction center composed of proteins and pigments, where the light energy is converted into chemical energy.

Pl. an·ten·nas A metallic apparatus for sending or receiving electromagnetic waves such as radio waves.

A feeler organ on the head of an insect, crab, or other animal. 17

An apparatus to receive or transmit electromagnetic waves and convert respectively to or from an electrical signal.

(nautical) The spar to which a lateen sail is attached, which is then hoisted up the mast.

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.

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.

An electrical device that sends or receives radio or television signals
