The polarization of an antenna describes the direction in which the oscillations of the electric field propagate. One differentiates between horizontal and vertical linear polarization (VP), and right-handed circular polarization (RHCP). Transmitting and receiving antennas should have the same polarization. The use of unequal polarized antennas can lead to losses or no radio connection at all.

Directional antennas for 869 MHz

A directional antenna focuses its radiation density in a specific direction. Due to its directivity, interfering transmitters placed outside of primary or secondary lobes are muted, and the antenna increases its reach in beam direction. Consequently the antenna radiates in one direction only.
