    • A decoder circuit including: a charge-up transistor for maintaining the content of an input address signal; a power supply switching transistor for controlling a charge-up current which is supplied to the charge-up transistor; a predetermined number of selection transistors which are connected at a connection point between the charge-up transistor and the power supply switching transistor so as to select an output word line, and; a bootstrap transistor which is connected to an opposite side of the connection point with respect to the charge-up transistor. The present invention enables the driving of the charge-up transistor with clock pulses having a potential level higher than the power supply line voltage V.sub.DD. The present invention also enables the driving of the power supply switching transistor by clock pulses having a potential level higher than V.sub.DD +V.sub.th wherein V.sub.+h equals the threshold voltage of the power supply switching transistor.

    • A preferably vertically oriented dipole antenna structure comprises a downwardly extending coaxial cable-like connector at the bottom of the structure attached to and insulated from a dipole element-forming sleeve whose upper end is rigidly connected to an insulating housing. The upper end of the housing supports a dipole element-forming rod extending vertically upwardly therefrom. The coaxial cable-type connector includes an outer rotatable conductive sleeve extending coaxially of the dipole element-forming sleeve and a central downwardly extending plug-in pin, the sleeve and the plug-in pin being coupled and connected to a cable extending through the dipole element-forming sleeve to a point within the insulating housing where a pair of cable conductors make connection to inductive coupling means for coupling signals between said conductors and the inner ends of the dipole element-forming sleeve and rod.
