I’d like to share the design files with\nthe amateur community, inviting people to build and improve on this design.\n\n\n\nThis design heavily leverages the previous excellent work by Tony Monteiro\n(AA2TX), who created and published the paper: “A Parasitic Lindenblad\nAntenna for 70cm” AMSAT Proceedings 2006. The AA2TX design uses a central\ndriven dipole surrounded by four tilted parasitic elements.\n\n\n\nOne of the biggest challenges to construct the AA2TX design is holding the\nparasitic elements in the crazy geometry defined by a Lindenblad\nconfiguration. The AA2TX design used irrigation parts, requiring careful\nalignment by hand and tedious bonding operations. Today with the\navailability of 3D printing it is possible to remove literally all the\ncritical alignments, designing these spacings and angles into the 3D\nprinted part!\n\n\n\nDesign files, pictures and construction notes can be found on Thingiverse\n(search for my call sign K7ZOO). I welcome any ideas for improvement and\nwould really enjoy seeing the results of any construction efforts.\n\n\n\nde K7ZOO\n", "attachments": [] }
