PURPOSE: An RF cable shield device of a wireless local loop system is provided to maximize efficiency in shielding of an RF cable by coupling a separate structure on an empty space of a shield structure. CONSTITUTION: A joint box shields a circuit board by being attached on an RF board. A concave pass groove is formed on one side surface of the joint box and allows an RF cable(200) to be installed thereon. Concave sliding grooves are formed along an operating direction on both sides of an inside wall of the pass groove. An insert member(20) is inserted into the sliding groove by means of a slide protrusion. An insert hole is formed to permit the RF cable(200) to be inserted into the insert member(20). A fixed protrusion(23) has the circuit board being coupled on a front end surface thereof. The pass groove is sealed by the insert member. The RF cable is inserted through the insert hole of the insert member to be fixed.
