Abstract
An antenna assembly having a pair of feed conductive elements directed in divergent directions, with each pair of conductive elements including a conical sheet conductor and a cylindrical sheet conductor, and radiating wire conductors extending away from each cylindrical sheet conductor. A balun feed system is defined between the pair of conical sheet conductors. A plurality of ferrite-cored inductors are provided on the wire conductors. A tubular radome assembly protects at least the radiating wire conductors from damage from external forces.
Claims21
An antenna assembly comprising:
- a pair of conductive feed elements directed in divergent directions, with each of the pair of conductive elements including a first generally conical sheet conductor and a first generally cylindrical sheet conductor, and a plurality of radiating wire conductors conductively attached to and extending away from the cylindrical sheet conductors, with at least some of the plurality of radiating wire elements include ferrite-cored inductors.
An antenna assembly comprising:
- an upper feed element including a first generally cylindrical sheet conductor and a first generally conical sheet conductor, with the first cylindrical sheet conductor conductively attached to a first plurality of radiating wire conductors, said wire conductors extending away from the first cylindrical sheet conductor, and with a plurality of wire conductors including ferrite-cored inductors;
- a lower feed element including a second generally conical sheet conductor and a second generally cylindrical sheet conductor, with the second cylindrical sheet conductor attached to a second plurality of radiating wire conductors extending away from the second cylindrical sheet conductor, said second plurality of radiating wire conductors extending in generally opposite directions as compared to the first plurality of radiating wire conductors, and with a plurality of wire conductors including ferrite-cored inductors;
- and
- a feedpoint adapted for connection to an RF transceiver, said feedpoint being defined between the first cylindrical sheet conductor and the second cylindrical sheet conductor of the upper and lower feed elements.

An antenna assembly comprising:
- an upper feed element including a first generally cylindrical sheet conductor and a first generally conical sheet conductor, with the first cylindrical sheet conductor conductively attached to a first plurality of radiating wire conductors, said wire conductors extending away from the first cylindrical sheet conductor, and with a plurality of wire conductors including ferrite-cored inductors, wherein each of the wire conductors includes three inductors;
- a lower feed element including a second generally conical sheet conductor and a second generally cylindrical sheet conductor, with the second cylindrical sheet conductor attached to a second plurality of radiating wire conductors extending away from the second cylindrical sheet conductor, said second plurality of radiating wire conductors extending in generally opposite directions as compared to the first plurality of radiating wire conductors, and with a plurality of wire conductors including ferrite-cored inductors, wherein each of the wire conductors includes at least two inductors, said plurality of radiating wire conductors being generally equally spaced apart around a generally circular surface;
- a feedpoint adapted for connection to an RF transceiver, said feedpoint being defined between the first cylindrical sheet conductor and the second cylindrical sheet conductor of the upper and lower feed elements;
- and
- a generally tubular radome enclosing the upper and lower feed elements.
