This 5 GHz dual port, dual polarized directional array antenna provides high gain and confined field, enabling a variety of broadband wireless applications. Due to its strong directivity, FM-TUBE is the ideal choice for applications in tunnels and closed environments such as Train to Ground communications for metros and underground mobility. The platform's discrete directional antenna technology combines two traditional antennas into a single package without sacrificing performance. Unlike traditional panel antennas, this end fire array antenna is physically and visually less obtrusive making it ideal for installations with limited space availability.
