VHF antenna bracket

thingiverse

This is part of the initial design of a bracket that will hold a VHF antenna. The bracket will be mounted on rails with a 19mm diameter. It consists of two parts, and other necessary components were sourced from an existing mount. A picture of the original style of mount is provided for reference. Upon assembling the unit, several improvements have been noted: The holes in the lower section could be changed to hex shape to secure nuts without them turning. At the time of design, the orientation of cap screws hadn't been decided yet. Taking a further skim from the mating faces may be beneficial - 0.5mm had already been removed, and an additional 0.2 to 0.5mm could be taken off each face to see if it increases clamping force, although it is adequate as it stands. Another modification that could be attempted is reducing the diameter of the through holes from 4mm to a smaller size. The design was initially created with 4mm stainless steel cap screws in mind, 25mm long. If one half of the model has the hole diameter reduced, then a screw thread could be applied to enable cap screws to bite into the material without using nuts. If anyone out there creates the final part, please share it and let me know. The file format is SketchUp 16, and ".skp" files won't open in earlier versions - sorry. Some of the design may appear crude with small errors, as I am new to SketchUp 3D design, and some minor errors may be present in and around the "teeth" of the model. When printed, these are too small to detect. I have no idea how this will perform under real-world conditions at sea, and no stress analysis has been conducted, therefore if you print this unit and use it for anything, you do so at your own risk.
