Thanks for posting this; maybe a homemade helibowl is a good way to get a low-cost GPS antenna with full frequency coverage down to L5. In my search for survey-grade antennas at hobbyist prices, I ran across this, as posted on Michele Bavaro's blog: http://www.onetalent-gnss.com/announcements/anovelpowerfulantennanavxperience3gc http://docs.google.com/viewer?a=v&pid=sites&srcid=b25ldGFsZW50LWduc3MuY29tfHd3d3xneDo1NTdmMzQzMDljOGZmODJh http://www.navxperience.com/download/3G_C_english.pdf Most of the complexity seems to be in the combiner network, which, being a planar circuit, can be well modeled.
