Methods and systems for producing magnetic walls for use in a switchable or activated non-reciprocal antenna array are presently disclosed. The non-reciprocal antenna array includes a plurality of omni-directional antennas linearly aligned with a phase center of each omni-directional antenna antennas on a line. Each antenna of the plurality of omni-directional antennas has an antenna rotation respective to the line. The array also includes an antenna spacing between the antennas equaling 360 degrees divided by a quantity of antennas in a full operational wavelength. Additionally, the array includes a set of antenna feeds corresponding to one feed for each antenna. The set of antenna feeds is configured to selectively enable or disable the plurality of antennas. When the plurality of omni-directional antennas are enabled, the array has a composite radiation pattern in having a maximum in one direction perpendicular to the line and a minimum in an opposite direction.
