Abstract
A terminated, end-fed inverted V antenna provides continuous coverage over the 1.8 to 30 MHz frequency range. A special matching transformer is an integral part of the antenna system.
Claims5
A wideband coaxial cable fed antenna system for continuous coverage of the l.8 MHz to 30 MHz frequency spectrum comprising an antenna wire in an inverted V configuration having two wire segments sloping generally downward from an elevated middle portion of said antenna, a terminatng resistor connected between one end of said inverted V antenna wire and an electrical ground connection, and a radiofrequency transformer having a longitudinally laminated ferrite bar core of generally rectangular cross-section, a low impedance primary winding adapted for connection to a coaxial cable transmission line, and a high impedance secondary winding connected between the end of said inverted V antenna wire remote from said resistor terminated end and an electrical ground connection.
A wideband coaxial cable fed antenna system for continuous coverage of the l.8 MHz to 30 MHz frequency spectrum comprising an antenna wire in an inverted V configuration having two wire segments sloping generally downward from an elevated middle portion of said antenna, at least one counterpoise wire located beneath said antenna wire extending generally horizontally between the ends of said inverted V antenna wire, a terminating resistor connected between one end of said inverted V antenna wire and said counterpoise wire, a radiofrequency transformer having a longitudinally laminated ferrite bar core of generally rectangular cross-section, a low impedance primary winding adapted for connection to a coaxial cable transmission line, and a high impedance secondary winding connected between the end of said inverted V antenna wire remote from said resistance terminated end and said counterpoise wire.
