The NLM-915 Near Field Loop design offers maximum power density in close proximity to the reader antenna. The Read Range for this reader antenna is Tag Dependent, but it is typically up to 3 feet. Maximum power input for the reader antenna is 2 watts. Nearfield Loop Antennas are very directional with superior isolation. Specifically, the characteristics of the antenna provide high forward directionality with extreme isolation adjacent to the antenna. The result is better performance and fewer instances of misread tags.
