Abstract: The DSS Uni-Mount is a ¼″ aluminum plate which is designed to mount a standard DSS (small dish) mounting arm to the gable end or hip edge of most residences or structures. This device virtually eliminates the need for roof penetrations in order to mount a DSS satellite dish. The top of the DSS Uni-Mount is machined at a roof angle of 5 & 12 and is designed for application to the gable end of a structure. It accommodates roof pitches from 4 & 12 thru 8 & 12. The bottom is cut at 90° to the sides thus enabling mounting to flat or hip portion of the roof line by inversion of the unit. A total of eight ⅜″ diameter holes are drilled thru the Uni-Mount in strategic places to allow the installer to match the DSS mounting arm holes with the DSS Uni-Mount plate. Lag bolts and machine bolts are then screwed thru and to the DSS Uni-Mount in order to secure the DSS mounting arm to the gable or eaves of the roofline.
