Omni Omnidirectional antennas radiate power uniformly in every direction on the horizontal plane. Most access points and GAIN client devices have LOW omnidirectional antennas.

Panel A flat antenna with a radiation lobe similar to a cone. It is HIGH GAIN directional and is normally used for point-to-point links or at the end-points of a pointto-multipoint network.

Parabolic A dish-shaped, directional HIGH GAIN antenna with a radiation lobe similar to that of a panel antenna. It is usually larger than a panel and has a higher gain. Parabolic antennas are Side View suitable for long distance Side View point-to-point links.

Sector A flat antenna with a radiation HIGH lobe similarGAIN to a cone with an elliptical footprint. It is directional and is normally used in the central site of a point-to-multipoint network. Side View

Defines the position in space of electrical and magnetic LOW GAINfields. The best signal transfer happens when both transmitting and receiving antennas have the same polarization. A 90° difference in polarization between transmitting and receiving antennas may produce up to Side View -30dB of signal attenuation.

the signal in a 360° belt around it. The higher the gain, the thinner the belt, resulting in a better signal far from the antenna — but a narrower communication area. Side View

Panel and parabolic antennas have a nearly circular footprint. Low gain panels can be used for both short distance point-to-point and point-to-multipoint links as well as straight roads coverage. High-gain panel and parabolic antennas

Loss Loss is the attenuation, or reduction in power, of a system, expressed in dB. All cables and connector devices have a loss variable and must be considered when designing a wireless system, especially when directional antennas are used.

produce such a small spot that they should be deployed only in medium- to long-distance point-to-point links. A sector antenna footprint is a horizontal ellipse with a width of 30°, 60°, 90° or 120°. High gain sector antennas have a vertically thinner footprint while keeping the same horizontal width, suited for the central site of a point-to-multipoint link or coverage of a certain “sector” in mobile networks.
