Claims15
A broadcast antenna including a first tubular conductor, a second tubular conductor, said first conductor being inside said second conductor,
- a centering structure, said centering structure extending between said first and second tubular structures to align same,
- a series of slots, said series of slots extending through said second conductor,
- an electromagnetic coupler, said electromagnetic coupler being located adjacent to said slots, and said first conductor being discontinuous along its longitudinal axis.
A broadcast antenna including a first tubular conductor, a second tubular conductor, said first conductor being inside said second conductor, said first conductor being discontinuous substantially at its longitudinal center to create a split,
- a third conductor, said third conductor being inside said first conductor and joining with same at its split,
- a centering structure, said centering structure extending between said first and second tubular structures to align same,
- a series of slots, said series of slots extending through said second conductor,
- and electromagnetic coupler, said electromagnetic coupler being located adjacent to said slots.
