Rupp Threaded Upper Antenna Support Assembly

This Rupp Threaded Upper Antenna Support Assembly is the top half of Rupp's antenna mounting system, built to pair with one of the brand's antenna base assemblies rather than serve as a standalone mount. It includes a forged aluminum yoke with a 7/8-14 thread, part number 09-1260-23, the component that actually grips the antenna. That yoke is the piece that determines whether the antenna sits securely once the whole assembly is put together.

A two-piece antenna collar, part number 09-1258-2PC, is sized for 1.5-inch OD antennas and clamps around the antenna shaft to hold it securely in the yoke. A black anodized jam nut, part number 03-1103-23, locks that connection in place so it won't work loose from vibration underway. Together, these three components form a complete upper assembly rather than a collection of loose parts.

Antenna collar options are selected from a drop-down menu at purchase, so it's worth confirming the exact collar size needed before ordering. Getting that measurement right the first time avoids a return trip for a different collar size down the line. A quick check of the antenna's own OD spec before checkout is the easiest way to confirm the right fit. Check out the rest of our marine antennas.
