Micha\u0142 S\u0142omkowski, SP3OHM, is building a QO-100 station in Poland. He printed the IceConeFeed DIY package<\/a>, wound the helix himself and sent three photos. His report: “I assembled the helix according to your design, works perfectly!”<\/p>\n\n\n\n

The DIY IceConeFeed is the open-source version of our QO-100 dual feed: a 3.5-turn helix for the 2.4 GHz uplink in front of a reflector disc, the unmodified LNB receiving the 10 GHz downlink through the centre. STL files, reflector drawing and tuning procedure are in the package; the procedure is in the build instructions<\/a>. The assembled and tuned version is the IceConeFeed v2.1<\/a>.<\/p>\n\n\n\n
