With the development of the Internet and communication technology, the demand for antennas has been increasing, and technology has also been improved.
Most FRP antennas are coaxial antennas with FRP tubes as covers, which have a large gain and a long size and are suitable to be used as base station antennas. However, the vertical angle is small, the signal can only be transmitted at 6 to 8 degrees horizontally. Therefore, FRP antennas are widely used for wireless coverage in plains and wireless coverage in the same horizontal position environment. If installed at a higher position, the signal can only be transmitted to a farther position, but the place near or with a height difference cannot be covered.
The most essential difference between FRP antennas and ordinary antennas is the difference in tightness and waterproofness. The working principle of FRP antenna and the ordinary antenna is the same. The glass fiber reinforced plastic antenna is encapsulated by a high-strength glass fiber tube, which is resistant to wind, moisture and smoke corrosion. It has high reliability and is suitable for outdoor use. However, ordinary antennas are not so tight and waterproof, therefore are generally for indoor use.
