  • Patent number: 10893264
    Abstract: A signal strength meter/indicator for use with an over-the-air broadcast television signal receiving antenna includes an input bandpass filter circuit, a first preamplifier circuit, a controllable variable attenuator circuit, a second preamplifier circuit, a splitter, an output bandpass filter circuit, a VHF/UHF filter circuit, a power detector circuit, a microcontroller and a display. The microcontroller, the controllable variable attenuator circuit, the second preamplifier circuit, the splitter, the VHF/UHF filter circuit and the power detector circuit together define an AGC circuit which adjustably controls the power level of an output signal provided to a television.

  • Patent number: 10541465
    Abstract: An antenna device includes a housing defining an interior cavity, a UHF antenna element, two VHF antenna elements and two WiFi antenna elements. The antenna elements are mounted to the housing and are selectively adjustable between a vertical, upright position and a folded, horizontal position. The antenna elements are situated on the housing to provide an omni-directional antenna pattern for receiving broadcast signals. Antenna circuitry provided within the interior cavity of the housing receives signals from the antenna elements and generates an output signal that is provided to at least one output connector mounted on the housing or on one or more signal cables extending therefrom and to an external electronic device connected thereto.

  • Patent number: 10522907
    Abstract: An antenna system for receiving over-the-air broadcast television signals includes a steerable directional antenna, a pedestal on which the directional antenna is rotatably mounted, a stepper motor to effect rotation of the steerable directional antenna, and a control circuit. The control circuit receives a control signal and causes the stepper motor to effect rotation of the steerable directional antenna. The directional antenna is steered such that its main lobe is generally directed to a television signal transmitting antenna selected by the user of the antenna system. The steering of the directional antenna is based on geographic location information associated with the television signal transmitting antenna.

  • Publication number: 20190214701
    Abstract: A retractable antenna assembly includes a planar antenna and a retraction mechanism. The planar antenna is affixed to the retraction mechanism and is selectively extendable and retractable therefrom. The planar antenna includes an antenna element having one or more antenna element segments. The retraction mechanism includes an elongated main body that is operatively coupled to at least two end brackets that mount the retraction mechanism to a supporting structure. The elongated main body includes a tubular sidewall having an outer surface that defines an interior space in which a cable and a preamplifier circuit are situated.

  • Patent number: 9312599
    Abstract: An antenna device includes a housing defining an interior cavity, and an RF antenna situated within the housing. The RF antenna receives high definition television signals broadcast over the air. An MHL connector is mounted on the housing. An external audio or video streaming signal device is coupleable to the MHL connector. An MHL to HDMI converter circuit situated within the interior cavity of the housing receives signals from the external audio or video streaming signal device and processes these signals into an HDMI signal format. The HDMI signals are provided on an HDMI output connector mounted on the housing. RF signals from the RF antenna are provided to an RF coaxial cable connector also mounted on the housing.

  • Patent number: 8299976
    Abstract: An antenna structure for receiving digital television broadcast signals includes a vase antenna housing having a generally hourglass shape with conically-shaped upper and lower segments joined together to define a narrower diameter middle portion. The antenna structure further includes a signal receiving antenna etched on the inner surface of the vase antenna housing. The signal receiving antenna conforms to the shape of the vase antenna housing and thereby exhibits an arcuate, partial hourglass shape. The signal receiving antenna may be a cloverleaf antenna or a spiral antenna.
