Abstract: An indoor television antenna has a bypassable amplifier circuit, which is user-controllable to switch between an amplification signal path and a unity gain signal path. The amplifier circuit, also referred to herein as a television signal switching circuit, includes a first switching circuit, a second switching circuit, a third switching circuit and a switching control circuit. The first switching circuit is coupled to the second switching circuit by the amplification and unity gain signal paths, which are substantially isolated from each other. An input of the first switching circuit is responsive to an antenna, and an output of the second switching circuit is coupled to a first input of the third switching circuit. A second input of the third switching circuit is coupled to a game port signal, and an output of the third switching circuit is ultimately coupled to a television receiver.

Abstract: A wireless receiving subsystem operatively connectable to a broadcast receiver unit having a frequency tuner has an antenna with a feed point, an amplifier located essentially at the feed point, and a transmission line extending from the feed point of the antenna and the amplifier to a signal input of the broadcast receiver unit. The transmission line having a pair of conductors, for example, coaxial conductors. A manually operated switch is disposed in the transmission line for applying a DC voltage across the conductors, while a relay switch is operatively connected to the transmission line for changing a connection state of the amplifier to the transmission line in response to the voltage.

Abstract: An antenna assembly is disclosed that comprises a terrestrial antenna and a support that mounts the antenna assembly on a satellite dish antenna. The satellite dish antenna has a convex/concave configuration, a periphery, a front signal receiving surface. The terrestrial antenna comprises a pair of dipoles. A power amplifier has an input connected to the terrestrial antenna to receive and amplify its terrestrial video signal. A diplexer is further provided and has first and second input terminals and an output terminal. The second input terminal is connected to the power amplifier to receive the amplified terrestrial video signal. The first input terminal is adapted to be connected to the satellite dish to receive the satellite video signal. The diplexer operates to sum the amplified terrestrial signal and the satellite video signal to provide an aggregate signal to the output terminal.

Abstract: In an antenna system with an antenna disposed outside a building structure, a motor is operatively connected to the antenna for moving the antenna about at least one rotation axis. A wireless control signal receiver is provided for receiving a short-range wireless channel selection signal identifying a broadcast channel. The signal receiver is operatively connected to the motor for energizing the motor in response to the wireless channel selection signal. The signal receiver is an infrared signal receiver located inside the building structure. The antenna system then further includes a signal transmission link extending between the infrared signal receiver and the motor for enabling control of the motor by the infrared signal receiver. Generally, the transmission link is an electrical conductor. However, it is alternatively possible for the link to be a short-range radio link.
