Breakthrough in Outdoor Waterproof Omnidirectional Antenna Technology

With the accelerated development of 5G-A, Industrial IoT, and smart city construction, the requirements for the adaptability of outdoor communication equipment to extreme environments are becoming increasingly stringent. Recently, the field of outdoor waterproof omnidirectional antennas has seen several technological innovations, achieving key breakthroughs in material selection, structural design, and performance optimization, providing core support for stable communication in remote areas and harsh weather conditions.

Material innovation has become a key factor in improving the environmental tolerance of antennas. The industry widely adopts fiberglass reinforced plastic (FRP) to replace traditional metal shells, achieving a leap in performance due to its lightweight and corrosion-resistant properties. One 1.2GHz FRP omnidirectional antenna weighs only 0.39kg, less than one-third the weight of a comparable metal antenna. Furthermore, its molding process creates a ribbed structure that can withstand the impact of a Category 12 typhoon with speeds up to 45m/s. Combined with an anti-UV gel coat layer, it achieves a wide operating temperature range of -45℃ to +85℃, with a waterproof and dustproof rating of IP67, demonstrating excellent performance in coastal salt spray and desert arid environments.

Significant improvements have been made in signal performance optimization through multi-element design and power supply technology. Some innovative products utilize a combination of FR4 plate and phosphor bronze in the element structure, enhancing gain through a three-unit element spring integrated design, achieving a peak gain of 10-12 dBi and improving signal transmission efficiency by 12%. Simultaneously, the application of balanced power supply technology keeps the penetration loss of high-frequency signals
