Overview Lightweight and durable dipole link insulator designed specifically for Wago 221-412 connectors. Ideal for portable amateur radio setups (SOTA, POTA, field days) to quickly connect or disconnect wire segments and change bands on linked dipoles.
Features
Strain Relief: Relieves wire tension so the Wago connector isn't supporting mechanical load.
Wire Compatibility: Designed for wire diameters up to 3.5 mm max.
Snug Fit: Keeps the Wago 221-412 securely locked in place while remaining easy to open.
Compact & Ultra-light: Minimal weight for portable antenna wire support.
Recommended Print Settings
Material: PETG, ASA, or ABS (recommended for outdoor use and UV resistance).
Layer Height: 0.20 mm
Infill: 25% to 100% (for maximum mechanical strength)
Perimeters/Walls: 2 or 4 walls
Supports: No
IMPORTANT: How a Linked Dipole Works / Clarification
Please note: This model is NOT a central feedpoint for your coaxial cable. It is a band-link insulator designed for multi-band linked dipoles (popular for SOTA / POTA).
The 3D-printed body acts as a mechanical insulator and strain relief to keep the antenna wires physically secured.
The Wago 221-412 acts as an electrical jumper/switch:
Connected: Connects two wire segments to operate on a lower frequency (e.g., 40m).
Disconnected: Isolates the two wire segments, shortening the antenna length to operate on a higher frequency (e.g., 20m).
Your coaxial feeder connects to the main center insulator, NOT to these link points.
