A portable dipole feedpoint and wire winder in one piece, with a hanging point and three-hole wire strain relief. Size: 75 × 140 × 24 mm; BNC cutout: 10.1 mm.
Hardware
Antenna wire and suspension cord
Printing
Suggested: PETG, 0.20 mm layers, 5 walls, 100% infill. Print dipole_winder.stl at 100% scale, flat-back down, BNC shelf upright. Supports are not intended.
Assembly
Dry-fit the BNC with its barrel pointing down and shell solder tag pointing outward, away from the frame. Tie the suspension cord behind the frame.
Front means the BNC shelf side. Weave each leg inward through its three holes: back-to-front, front-to-back, back-to-front; threading.svg shows the route. Leave slack to the connector and tug each leg to check the inner tail stays slack. Solder one leg to the center cup and the other to the shell solder tag.
Check continuity from BNC center to one leg and shell to the other, with no center-to-shell short. Unwind both legs fully before operating. I use a separate, reusable feedpoint choke: RG-316 coax from ABR Industries with seven mix 31 ferrite beads.
CAD renders shown; printed connector fit and wire grip still need checking.
For OpenSCAD editing, keep all three .scad files together.
