ParabolicAntenna

werwe

Parabolic Antenna are directional. They are ideal for PointToPoint (Back Bone) links running IBSS.

The higher the gain, the smaller the beam width

Typical gain range are 15dbi - 24dbi

It is a common misconception that it's the parabolic dish which increases the gain of the antenna. Instead, it's the projected aperture that provides the gain. Therefore, the higher the gain, the larger the parabolic dish. Bending the parabolic section of the antenna to be more concave will not increase the antenna's performance.

Examples of these are GalaxyAntenna

A different approach has emerged from Stan Swan and associates at Massey (NZ), who have successfully used Chinese cookware and USB WiFi adaptors to produce highly effective devices that are capable of several kilometer links. See External linkStan Swan's site for further details.
