The LKAV-3719 is an 802.11AN 300Mbps 5.8G 800mW high-bandwidth wireless bridge specifically designed for ultra-long-distance wireless bridging. It can reach an effective bandwidth of 80Mbps at 15km under barrier-free conditions. It can be applied to point-to-point over 20km. For bridging applications, the cast aluminum shell can not only effectively resist aging and extend the service life, but also can effectively dissipate heat to ensure stable operation. The built-in high-performance antenna designed with high-frequency materials is lightweight and has excellent RF performance, is far better than the external 23dBi antenna on the market, it is not only easier to install, but also more cost-effective.
