2M EZ Lindenblad Antenna

thingiverse

I've remixed this original post from Die_Bastelkammer. Included are the .pdf and Sketchup files for your reference, allowing you to modify them as needed. Living in a small town made sourcing local materials a priority, so I adapted the T design to accept 1/2" copper tubing for elements and 1/2" EMT conduit for the boom. Notably, 1/2" conduit has a slightly larger ID than 1/2" copper pipe; however, this antenna is quite forgiving in terms of build materials and methods used. To achieve proper element spacing, simply cut copper pipes to length, slip them onto the T until they touch the center box, and you're good to go. Make sure to print at 100% infill for maximum rigidity. I've successfully printed with PLA, but ABS would work just as well; my prints were done at a .20 resolution.
