A new tuning probe for slide-screw impedance tuners uses a simplified semi-cylindrical tubular form. This ensures reduced manufacturing cost and high machining tolerance for probes using galvanic ground contact. RF performance matches or exceeds traditional cubical probes both using galvanic and capacitive ground contacts.
