An L-shaped probe (5) extends inside a horn radiator (1) closed at one end by a rear wall (2). The probe (5) has a longitudinal branch (51) parallel to the longitudinal axis of the horn (1) and a transverse branch (52) in a plane perpendicular to the longitunal axis of the horn (1). The longitudinal branch (51) extends from the rear wall (2) of the horn for a predetermined length (H) at a predetermined distance from the side wall of the horn (1) and is connected through the rear wall (2) of the horn to the central conductor of a coxial cable. The transverse branch (52) of the probe has a predetermined length (L) and a predetermined width (d). The values of the parameters (H, D, L and d) are chosen so as to produce the best stationary wave of voltage. The invention is advantageously used on spacecraft, for example.
