  • Patent number: 5986610
    Abstract: An electric dipole antenna includes a first and a second arm extending along a dipole axis away from a feed gap in substantially opposite directions. A first and a second end body are operatively coupled to opposite ends of the first and the second arms. Each end body has a width dimension which extends perpendicular to the dipole axis. A dipole length dimension extends along the dipole axis through the first and the second arms and the first and the second end bodies. A current conduction circuit provides a radiation field for the electric dipole antenna. The circuit passes along the first and the second arms and around a closed perimeter of the first and the second end bodies. As a result, the electric dipole antenna exhibits a series resonant frequency at a wavelength which is at least eight times the dipole length dimension. In addition, an electric monopole antenna design is used. The monopole is situated over a conducting ground plane which reflects the above-ground plane portion of the antenna.

  • Patent number: 5970645
    Abstract: A fish bite indicator system includes a flag post having a flag attached to the post by a removable collar. The post is further attached to an elbow member by a coil. The elbow member is attachable to a pole of a fishing rod. The coil urges the post into a perpendicular orientation with respect to the pole. A retention assembly is provided for holding the post in a parallel orientation when in a set position. The fishing line passes through the retention assembly such that sufficient pull on the fishing line disengages the retention assembly such that the post returns to the perpendicular orientation. The fish bite indicating system is also usable without the retention assembly by retaining the post using the handle of a spinning reel. The elbow member is adjustably attachable to the pole using a bolt and nut holding a pair of rubber washers around the pole.
