QFH Antenna

thingiverse

I built a QFH Antenna for use with my SDR radio to pick up and decode weather satellites. The rest of the build I made using pipe and coax I already had on hand. Support pipe is designed to be 40mm in diameter, similar to this: http://www.diy.com/departments/floplast-push-fit-waste-pipe-dia40mm-white/152664_BQ.prd Arms for the coax are made from 21.5mm pipe, like this: http://www.diy.com/departments/floplast-overflow-waste-pipe-dia215mm-white/109187_BQ.prd I used coax with a 7mm outer diameter, standard shielded and satellite cable. You can use the calculator here to calculate the rest of the sizes: http://jcoppens.com/ant/qfh/calc.en.php I've included both STL files and Fusion 360 source files so you can modify them as needed.
