2M QFH Antenna parts set
thingiverse
These are 3D printed parts for a 2 meter quadrifilar helix (QFH) antenna as described by G4ILO at http://www.g4ilo.com/qfh.html. My variant doesn't use uPVC plumbing pipe, but electrical installation tubes 16mm (5/8") and 19mm (3/4") diameter, the standard here. This doesn't make a very rigid construction, but good enough for evaluation purposes. It is intended for outdoor usage. These antenna's are used for satellite reception, like weather images. For more info, see: https://network.satnogs.org/ The antenna is currently active as https://network.satnogs.org/stations/1579/ All the designs are in the staticQFHset5.scad file, which is quite messy. Maybe I'll fix that later.
