Jelmer, See my article on a 75' vertical for 80/160 in June 2004 QST in which I use L-networks for feedpoint matching ... very simple and far less complex than any Gamma matching schemes. Also see July 2004 QST "Feedback" for an error correction. 73, Dave, K1FK, Fort Kent., ME ARRL Life Member/Diamond Club QCWA Distinguished Member
