A system for automated installation of a communication line using an optimal route between a source location and a destination location is disclosed. The assembly comprises a first length of tubing made of a first material. The open area in the insulating layer includes an inclined side wall at a positive angle of inclination. The filtered liquid flows from the collector through a passage into a UV chamber. In some embodiments at least one of the nodes has a plurality of output queues. The connecting arm connects to the resonator body at a non-nodal point so that it is not connected to a normal position where fixed connections are made.
