The PA805Z2-RSMA is a passive directional antenna that improves RF transmission of all GLXD systems. By suppressing the RF signals that run alongside the directional axis, an immovable operating stability is achieved. Especially in environments with other 2.4GHz devices an important tool for improving radio transmission. When the antennas are installed remotely, they can be directly aligned with the transmitters to guarantee transmission reliability. The antenna can be mounted on a microphone stand or on the wall with a separate mounting bracket.
