This coupler is an easily adjustable mounting device for 1" tape measure yagi elements on a 3/4" (ID) PVC pipe boom. The yagi elements secure with 3/4" to 1 3/4" hose clamps. The hose clamps act as friction locks for the yagi elements.
This design is jointly owned by myself and Robert Meade Thingiverse Link here
Supports are required for the entire model. I printed with PETG but PLA will also work (although soldering will be riskier). Layer height does not matter. I printed with 30% infill for the print
