I would strongly urge that you get ON4UN's book, "Antennas and
Techniques For Low Band DXing" and read chapter 11... He analyzes a case
which is exactly what you are trying to do... In figure 11.25 he shows
the network and the relay switching so that the transmitter sees 50 ohms
nominal, for both in phase and out of phase conditions... His design
example is for 80 meters, but using his software you can calculate the
values for the matching network for 160, quickly and easily...
Cheers ... Denny
