I was so happy with the puk on a metal plate I decided to pick up a decent GPS antenna from ebay. HUBER+SUHNER 1315.17.0008 1575MHz 34dB N female gps antenna antenne Aerial (ebay search terms)
This is now coupled to a short length (circa 6m) of LMR400. That really is the best I can do now, short of re-locating the antenna on the roof. The GPS antenna was £15 delivered from China, and it would seem to be the real deal.
