A method for receiving a message and outputting the portion of the message that is within the capabilities of the receiver of a wireless device. Each RF modules may have a wedge-like shape such that the RF modules may be adjacently affixed to one another in spherical cluster, thereby providing multi-sector coverage while maintaining a relatively compact active antenna installation. A lever coupled to the hitch is operated to position the hitch for insertion into a receiver pocket of the next cart. This is accomplished by routing the ion beam through electrodes having potentials developed thereacross.
