MULTI-BAND ROD ANTENNA FOR BROADCAST

摘要

PURPOSE: A rod antenna for multiband broadcast is provided to include a lower sleeve, a helical conductor, and a linear conductor, thereby being operative without an increase of physical length in multi bands. CONSTITUTION: One end of a second antenna is connected electrically with a lower-part electric supplier (101). A third antenna (130) is connected electrically with the lower-part electric supplier. The third antenna comprises a linear conductor (131) and a second dielectric (132). The linear conductor is disposed inside a helical conductor. The second dielectric isolates the helical conductor and the linear conductor at a fixed interval.
