Abstract: Presently disclosed is an antenna system having an array of ridged waveguide Vivaldi radiator (RWVR) antenna elements fed through a corporate network of suspended air striplines (SAS). The SAS transfers the electromagnetic energy to the radiating element via the ridged waveguide coupler. The Vivaldi radiator matches the output impedance of the ridged waveguide coupler/SAS to the impedance of the surrounding medium. Because the coupling method and the radiating elements are wideband mediums, this antenna array is capable of wideband operation. The physical dimensions of the resulting array are also not as sensitive to its electrical performance as other antenna designs since the bandwidth is quite large, reducing the occurrence of an out-of-specification antenna due to manufacturing tolerance build-up. This also reduces the complexity of the manufacturing process, which in turn lowers cost.

Abstract: A dumpster hose assembly operable to be mounted between a waste discharge pipe member on a recreational vehicle to a receiver member on a dumpster tank reservoir to remove waste waste products from a reservoir tank in the recreational vehicle. The recreational vehicle dumpster hose assembly includes 1) a female entrance and coupling member readily and releasably attachable to a male coupling member on the waste discharge pipe member on the recreational vehicle; and 2) a flexible hose member having one end connected to the female entrance end coupling member and an opposite end connected to a male discharge end coupling member. The male discharge end coupling member is readily connected to a female coupling member which, in turn, is connected to a swivel coupling member. The swivel coupling member is connected by a primary sleeve member to an entrance leg section on the receiver member for dumping waste products into the dumpster tank reservoir.
