The point of reference for specifying a polarization is looking at it from the transmitter of the signal. This can be visualized by imagining standing directly behind a radio antenna and looking in the direction it is aimed.

In the case of a horizontal polarization, the electric field will move sideways in a horizontal plane. Conversely, for vertical polarization, the electric field will oscillate up and down in a vertical plane. Linear polarization refers to an antenna system that is operating with Horizontal and Vertical polarization.

Image 1 shows horizontal H and vertical V polarizations. The two polarizations shown in image 1 would be considered orthogonal to each other. Orthogonality allows a given polarization of an antenna to only receive on its intended polarization, isolated from the orthogonal polarization, thus avoiding interference from energy on the orthogonal polarization. Taking the same analogy of standing behind the radio and looking in the direction of the signal, slant polarization is equivalent to taking a linear polarization radio and rotating it 45 degrees.

This would lead to a decreased signal strength at the receiving antenna.
