Characteristics of Outdoor Fiberglass Antennas

What are the antenna products in everyone's mind? Previously, telephones had antennas and walkie talkies had antennas, but have you understood the composition of antennas, fiberglass antennas, and so on Now let's talk about antennas
SMC is a type of sheet-like molded plastic, which is made from unsaturated polyester resin, glass fiber untwisted coarse yarn, and other matching materials through a specialized SMC molding machine. It is then thickened, cut, and solidified into a metal mold under high temperature and pressure. SMC, as an emerging fiberglass reinforced plastic, commonly known as outdoor fiberglass antennas, can be processed in several ways: hand layup molding, radiation molding, extrusion molding, winding molding, resin transfer molding, and compression molding. SMC and its molded products have the following characteristics: accurate size, good batch quality variability, light weight, high strength, and can achieve zero shrinkage rate. Compared to A-level appearance, it has a high level of mechanization and automation, and is suitable for products with high appearance quality requirements, large production capacity, and average thickness.
Traditional antennas such as steel plates and aluminum plates are made of metal materials, which are used in areas such as acid resistance, salt resistance, corrosion resistance, and alkali resistance, and can be used as composite materials for SMC non-metallic media. The American laboratory analyzed the surface data of SMC using infrared radiation and found that its surface was covered by additives, ultra-fine calcium carbonate, resin and other fillers, which had good acid resistance, water resistance, and corrosion resistance. The antenna reflection treatment of the data made the traditional metal data antenna easy to corrode. In areas near the sea, rainy and humid areas, and areas with acid rain, the advantages of this corroded SMC molded antenna are particularly prominent. The United States has conducted anti-corrosion experiments under more stringent conditions. At a high temperature of 50 ℃, the sample chemical environment was subjected to 130 types of high corrosiveness, and the experimental sample results showed only slight or no changes.
