What are Multi-Polarized Antennas?

Multi-polarized antennas are used to receive wireless internet signals. These signals are in a constant traffic jam in the airwaves, and multi-polarized antennas help clear the road. By accepting multiple types of radio signals, as opposed to the single type that many antennas use, this device can double signal strength. The antenna's ability to strengthen signals makes it popular in crowded areas with many obstructions such as buildings or trees. These antennas also can accept improvements that make its strong signal even more powerful.

A traditional wireless internet antenna will pull in either horizontal or vertical radio signals, known as the X and Y plane. Multi-polarized antennas are able to pick up not only the X and Y plane of radio waves surrounding it but also the angled Z plane. This antenna juggles between these three radio signals to find the strongest one and provide the best wireless connection possible for that location. This flexibility allows the antenna to switch between the three signals when traditional antennas fade or die completely.

Multi-polarized antennas are popular in places where obstructions are unavoidable. Outdoor locations such as the dense tree cover of recreational vehicle (RV) parks and campgrounds can be difficult to locate a signal without a multi-polarized antenna. This type of antenna is also popular in areas where there is a lot of radio traffic, such as a marina, because it can untangle the maze of signals to find the best option. Similarly, crowded office environments commonly have several different signals and physical obstructions that multi-polarized antennas can properly organize into a strong web connection.

Multi-polarized antennas are also coveted because they can improve signals with some minor tinkering. One important rule of thumb is to adjust the antenna at a 7- to 10-degree angle toward the signal source. This slight bend allows the antenna to fully pull in the three main signals available.

Another option to improve quality is to use an amplifier that allows the antenna to pull in a far greater range of signals. Always research local communication laws, because many governments restrict the size of amplified signals. For example, the United States has effective radiated power limitations for antennas.

When radio traffic and physical obstructions interfere with a strong wireless internet signal, multi-polarized antennas are the answer. By not only pulling in horizontal but also vertical and angled signals, this device provides the most powerful radio signal. And if that signal isn't strong enough, there are techniques to make the antenna reach even further.
