The system also includes a transmission line for connecting the antenna farm unit to the radio unit, where the transmission line has a first terminal and a second terminal, and where the first terminal of the transmission line is electrically connected to the multiplexer and the second terminal of the transmission line is electrically connected to the demultiplexer.

Abstract: An antenna system for a vehicle includes a first antenna array affixed to the vehicle and a remote antenna system. A first connector is affixed to the vehicle, and is connected to the controllable switch. The remote antenna system includes a second antenna array including a second active antenna and a wiring harness. The wiring harness includes a second signal lead connected to the second active antenna, a ground lead, and a second connector. The signal lead and the ground lead connect the second active antenna of the second antenna array to the second connector. The first connector is connectable to the second connector, and the switch array communicates signals from the second antenna array to the on-vehicle controller when the second connector of the second antenna array is connected to the first connector.

Abstract: A vehicle, an antenna assembly of the vehicle, and a method of assembling the antenna is disclosed. The vehicle includes a housing having a passage formed therethrough. A circuit board is disposed within the housing. An antenna element is coupled to the circuit board and passes through the passage. A plug fills an annular volume of the passage between the antenna element and the housing.

Abstract: A mount system, such as for a vehicle antenna, includes a module with a ground. A fastener extends into the module. A retainer clip moves from an undeployed position to a deployed position by operation of the fastener. The fastener extends through a deployment ramp block. The deployment ramp block engages and guides the retainer clip from the undeployed position to the deployed position, by operation of the fastener. The mount system is configured to effect grounding of the ground to the product and to retain the module in position on the product.

Abstract: A receiver for receiving radio frequency signals from a remote keyless entry system and another system includes a low noise amplifier for amplifying and increasing the range and sensitivity of the receiver, such that the receiver may receive signals at increased distances. A gain of the low noise amplifier is selectively controlled to cycle from a first gain level that provides for increased sensitivity and a second gain level that provides a lower sensitivity and a greater dynamic range or larger signal capacity.
