Overview

Laird SR Series dual-band tri-mode antenna offers the system integrator a perfect solution to indoor and outdoor wide area coverage wall-mount applications. While omni-directional antennas are well suited for installations where the antenna has a 360 degree unobstructed view of the coverage area wall mounting omni-directional antennas can create a number of system performance issues. Because the antenna radiates equally in all directions much of the power is radiated directly to the wall surface behind the antenna. This causes elements of the wall to become actual components of the antenna often causing multi-path nulls within the intended coverage area.

The SR Series antenna provides a solution for the most common coverage requirements. Its integrated backplane shields the radiating element from the wall eliminating any problems from wall construction components. The antenna's gain makes it a perfect replacement for typical high-performance omni-directional antennas. The result is solid consistent and uniform coverage within the intended coverage area.
