ANTENNA TOWER AND RADIATION IMMUNITY TESTING FACILITY USING SAME

摘要

PROBLEM TO BE SOLVED: To provide an antenna tower by which two radiation antennas are made independently movable. ;SOLUTION: The output of a first motor 29 is transmitted through a first gear 27 to a first belt 25 connected with and fixed in a first jig 31 holding a first radiation antenna 1 to move the first antenna 1 up and down. The output of a second motor 30 is transmitted through a second gear 28 to a second belt 26 connected with and fixed in a second jig 32 holding a second radiation antenna 2 to move the second antenna 2 up and down. Consequently, two radiation antennas 1, 2 can be moved independently by one vertically installed mast 20 for antenna movement and can be combined at optional positions in one and the same line.;COPYRIGHT: (C)1997,JPO
