What is Radom: Specifics, Types, and Application
A radome is a construction that allows providing sufficient security of an antenna from the influences of climatic factors, reduce an external impact on an antenna and protect it from rain and snow, as well as erosion effects.
There is a big variety of constructional and technological performance of radome that depends on antenna type and weather conditions. The main selection criteria for radomes for all types of antennas are rigidity, frequency range, radio transparency, required shape features, electromagnetic signal magnitude, shading of the aperture by the frame elements, materials, etc.
Today, the range of products on the market of radome allows you to choose the weatherproof product that will meet all your requirements and needs and will work well with your antenna or radar system.
Types of Radome
Modern industry offers three main types of radomes that largely differ in their characteristics and the choice of materials. There are such categories of radomes as composite, space frame and air inflatable radomes. Radome manufacturers strive to meet the needs of the market to the maximum, producing a diversity of radomes designed for a bunch of mechanisms such as radar systems, antennas, weather radar, air traffic control systems, etc.
The main type of composite radome is a sandwich radome. It is characterized by high rigidity and has the shell shape. A sandwich radome is a protective construction that is made of curved panels that attached to each other so they form a spherical dome.
Air Supported Radom
This category of radome – it is a soft slipcover filled with air. Considering the structural features, air-supported radome requires an uninterrupted power source to provide a stable air pressure inside the sphere. The main advantage of the air-inflated radome is that they allow minimizing interference in the frequency of the antenna signal due to the material. Using various types of fabrics, manufacturers can offer numerous variations of RF characteristics.
Space Frame Radom
This type of radome has a big rigidity, which consists of a set of triangle panels. Those elements are attached to each other so they form a securing dome. Such radomes guarantee the highest level of protection from all possible external factors. Space frame radome is mainly used in regions with extreme weather conditions.
