on the WA1QIX home page about class E PA's it was mentioned that sheilded cable with the sheild used as one conductor and the two inner cables could be used as a transformer without using a ferrite core , has any one tried this and if it did work what kind of dimentions were used. Second question has anyone tried a trifilar wound transformer on a pvc former with any sucess. My interest is 160 metres and a large PA coil does not present an issue.
