Methods and systems for establishing a non-line of sight millimeter wave connection that include a transmitter unit having beam-steering capability, a receiver unit having beam-steering capability, and a reflecting unit in a position having a line-of-sight path to the transmitter unit and the receiver unit. The reflecting unit includes an attachment mechanism configured to attach to a mounting point on an object or surface, a reflecting surface that is reflective to millimeter-wave radiation, and an adjustable pivot connected between the attachment mechanism and the reflecting surface configured to permit directional positioning of the reflecting surface relative to the attachment mechanism.
