An antenna having the property of radiating or receiving electromagnetic waves more effectively in some directions than others.

Antenna that transmits and receives signals in a narrow angle. Also see antenna. Contrast with omnidirectional antenna.

A TV or FM antenna that picks up signals better from one direction than another. Usually has two or more sections or elements for increasing directivity and must be oriented according to the signal being received.

An antenna, transmitter, or beacon which transmits its signal in a straight line.

An antenna in which the radiation pattern is not omnidirectional, i.e., a nonisotropic antenna.

An antenna for wireless equipment which sends or receives a propagated radio signal on the same axis as the corresponding antenna on the other end (with line-of-sight visibility between the two whenever possible). While omni-directional antennas are great for short range broadcasts because of their versatility, high gain directional antennas are recommended for most long range wireless video applications.

An antenna with a narrow coverage beam that can be positioned to point in a specific direction.

a good thing if you are a serious radio listener because it can diminish interference that's coming from another direction

an antenna that is designed or altered for the purpose of obtaining a non-circular radiation pattern

This term defines several types of antennae that redirect the signal received from a transmitter to enhance its strength in a certain direction, unlike an omnidirectional antenna.

Directional antennas focuses the radiation pattern in a specific direction. They are available in a variety of from factors and strengths. Directional antennas are useful in covering long hallways and in bridging two wireless networks together.

An antenna that concentrates transmission power into a direction such that coverage distance increases at the expense of coverage angle. Directional antenna types include yagi, patch, and parabolic dish.

An antenna or array of antennas designed to concentrate a radio signal in a particular area.

A transmitting aerial in which the energy radiated by a TV or radio station is concentrated in a particular direction.

An antenna with a radiation pattern that concentrates both the transmitting and receiving signal power into one favored direction.

An antenna or array of antennas that concentrates a radio signal in a particular direction.

an antenna that transmits or receives signals only in a narrow angle. Decatur offers police radar w/ K-Band Directional Antenna, such as Decatur Speed Trak Moving Police Radar and Decatur GVP-D Genesis VersaPak Directional Radar Handheld Cordless Police Radar Gun.

An antenna designed to transmit and receive RF energy in a specific direction(s).

An antenna that radiates most effectively in only one direction.

A directional antenna is an antenna which radiates greater power in one or more directions allowing for increased performance on transmit and receive and reduced interference from unwanted sources.
