A broadband communication system in which a central office is connected to a high speed network utilizes various LMDS architectures of the present invention to expand network capabilities. Each airfoil includes a blunt trailing edge, a substantially oval shaped suction side, and a substantially S-shaped pressure side. The plunger includes a head that is sealable within a recessed portion of the orifice to open or close the orifice. The first tapered end portion is formed at a first end of the balloon body portion. The example method still further includes, in response to the change in congestion state, communicating a flow control message to the data ingress module and, in response to the flow control message, modifying communication of the data traffic flow. A left receiver accommodation portion is configured to accommodate a left receiver block such that the left receiver block does not move during the gunsmithing activities.
