Skew is a term used in antenna engineering. It is a technique to improve the horizontal radiation pattern of a high power transmitter station . In a high power VHF or UHF station, usually the antenna system is constructed to broadcast to four directions each separated 90° from each other.
The line through segment AD and the line through segment B 1 B are skew lines because they are not in the same plane. In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.
Skew lines, neither parallel nor intersecting.; Skew normal distribution, a probability distribution; Skew field or division ring; Skew-Hermitian matrix; Skew lattice; Skew polygon, whose vertices do not lie on a plane
A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram , rather than the rectangle that is the plan view of a regular, or ...
a torsion angle between 30° to 90° and −30° to −90° is called synclinal (sc), also called gauche or skew [33] a torsion angle between 90° and 150° or −90° and −150° is called anticlinal (ac) a torsion angle between ±150° and 180° is called antiperiplanar (ap), also called anti-or trans-conformation
In the older notion of nonparametric skew, defined as () /, where is the mean, is the median, and is the standard deviation, the skewness is defined in terms of this relationship: positive/right nonparametric skew means the mean is greater than (to the right of) the median, while negative/left nonparametric skew means the mean is less than (to ...

In an oblique projection (at right), the projection lines are at a skew angle to the image plane. Every parallel projection has the following properties: It is uniquely defined by its projection plane Π and the direction v → {\displaystyle {\vec {v}}} of the (parallel) projection lines.
