Polarization
The polarization of an exterior antenna is an important factor to consider when choosing an antenna. The polarization of an antenna determines the orientation of the electromagnetic waves that the antenna transmits and receives. There are two main types of polarization: vertical and horizontal.
- Vertical polarization: In vertical polarization, the electromagnetic waves are oriented vertically, perpendicular to the ground. Vertical polarization is commonly used for antennas that are mounted on vertical surfaces, such as walls or poles.
- Horizontal polarization: In horizontal polarization, the electromagnetic waves are oriented horizontally, parallel to the ground. Horizontal polarization is commonly used for antennas that are mounted on horizontal surfaces, such as roofs or the ground.
It is important to match the polarization of the exterior antenna to the polarization of the wireless device that it is being used with. If the polarization of the antenna and the wireless device do not match, the signal strength will be reduced.
Here are some examples of how polarization is used in exterior antennas:
- Cellular antennas: Cellular antennas are typically vertically polarized. This is because cellular towers are typically mounted on vertical surfaces, such as buildings or towers.
- Wi-Fi antennas: Wi-Fi antennas can be either vertically or horizontally polarized. The polarization of a Wi-Fi antenna should match the polarization of the Wi-Fi router that it is being used with.
- Satellite antennas: Satellite antennas are typically horizontally polarized. This is because satellites are typically in orbit above the Earth, and the electromagnetic waves that they transmit and receive are oriented horizontally.
By understanding the polarization of exterior antennas, you can choose the right antenna for your needs and ensure that you have the best possible signal strength.
