I made remixed this insolator to use 300 ohm twinlead for a cheap 6m 2m 70cm collinear.
Instead of using 400ohm ladderline I chose to use 300 ohm twinlead for the phasing harnesses. I chopped off the center hole support to save on weight, wind resistance and printing time. I will use the original un-mixed insulator for the off center fed dipole to feed
the rest of the collinear antenna sections. The original author says M3x10mm cylinder head slotted Screws will hold these 2 pieces together.
